Thanks for the comment. You know, I've thought a lot about this, but I literally get *dozens* of messages every day from students who tell me that my face makes the learning feel more "personal," and that feel they can't learn from other online videos because of the lack of personal connection. Ultimately, it would ideal to have two versions of every video: with and without the head-on shot, and students could choose which is more effective for them. I'll get on it as soon as I have more time!
The ones would be better...as it makes us feel there is someone real explaining to us.... It just makes us understand it better than a video without a face... (like patrickJMT ☺ no offence )
You can separate the water back into hydrogen and oxygen, but to do that, you'll need to use all the energy (plus a little more) that the fuel cell made in the first place. So it can go back and forth, but not as a self-perpetuating energy source.
I really, really appreciate your use of a Boys and Girls Camp analogy. You really dumbed it down for me and now I understand what a fuel cell is and how it works. Thanks for the great vid!
you're so amazing. I wish you were my teacher, I didn't understand this until I watched your video.you deserve SO MUCH MORE CREDIT especially for your creative analogies. great job and thank you so much.
Great question! That's actually one of the problems with fuel cells. It takes a lot of energy to get those H2 molecules in the first place. Lots of electricity is required to break water apart and make H2--that's how we get most of the H2 used in cars and trucks. The problem? Using H2 in fuel cells is a super clean technology. Getting the H2 in the first place requires energy that may not be generated in particularly green ways.
I am currently teaching high school physics and chemistry as well, in Malaysia. Sometimes I feel I am making myself trouble to rethink the syllabus in order to present it in the way that is comprehensible by students, and your talk at TED inspire me that I am not alone in this quest. Thank you very much.
This guy has such a good mind at explaining things. I remember when i was researching how batteries worked it took a lot of effort to fininally figure out how they work. I wish this video was out a year ago lol!
Best chemistry teacher ever! I have been following this channel since 9th Std and am presently in 12th. He really makes the concepts crystal clear... His teaching style is superb!!!
You're amazing at teaching. Thank you for all the work you do for the average kid growing up in this busy world. You deserve many more views, but just know thousands of people across the world are thanking you everyday
I study chemical engineering. My teacher at uni has a very very high knowledge and tries to explain this on a very high level and this was my first time with fuel cell, so thank you for this video I finally understand it.
The Summer camp reference. 😂😂😂😂😂 P.S. Your teaching method is the BEST! Animated , concise , and.... compendius...... Thank you for your time , and effort 💜
You are one of the most talented and genius teachers. You have expertise to make the hardest topic very easy. This video is no less than masterpiece from your side. Love you ,Sir. You really deserved to be called Sir. ❤
Nice video. I see this as a great tool for teaching chemistry in middle school, but not so much help to college people. But to break the topic down and explain it as boy-girl posse means that you really understood the stuff, so great job!
Thanks so much for explaining that. Your are the only one so far speaking of these all important details - and the Catalyst !!. As with Solar panel "explanations", these thing just happen because the magician said so !
When the protons and the electrons are separated, the electrons gain electrical potential energy. The electrical device is placed along the electrons' path to be activated when the electrons pass through.
Physicist do not talk about the volume of the electron usually. The electron is considered as an elementary particle with no structure. It has mass, however, almost 2000 times smaller than that of the proton.
Thank you for the great explaination. I understood it really well, even tought another student, before we both had exams yesterday. It went really well. 😄
Actually, instead of an electrolyte, it is a proton exchange membrane so here, protons are delivered to the another side of the electrolyte where together it forms water.
The terms "proton exchange membrane" and "polymer electrolyte membrane" are used synonymously. So they are the same thing. And "polymer electrolyte membrane" is often shortened simply to "electrolyte" or "electrolyte membrane."
It was an amazing explanation. I have a question not entirely connected with this. This is a clean and safe energy, but (mind my lack of knowledge) is getting H2 and O2 molecules safe and clean without any waste too? Can we reverse the water into H2 and O2 to make use of it again?
Please teach at university cause there are many lecturers in uni just can't teach. It will make things easier for undergrads if you could be one of the lecturers
What is the catalyst made of? What is its chemical component and how is it obtained? Is the catalyst an integral part of the graphite plate or of the membrane that forms the electrolyte? Can you please elaborate? Some of us are interested not only in understanding but also in practical application...
if water (H2O) is a Covalent compound formed by sharing of electrons, why is it said (in case of fuel cells) that formation of water from hydrogen and oxygen is a redox reaction (transfer of electrons, not sharing). This would make it an ionic compound. Any insights? Note that, the concept of water being formed as a result of redox reaction is highlighted in fuel cells (which is the basic principle of fuel cells - generating electricity by exploiting this transfer of electrons)
***** Hi, I think that by a redox reaction it means that the hydrogen atom is broken down to electrons and protons which means that hydrogen is being reduced because the electrons break away from being an atom and eventually become connected with the oxygen atoms to form water. So I'm sure that when they mentioned 'Redox reactions" they had in mind that the oxygen atoms are causing the hydrogen atoms to break down into protons and electrons through which the oxygen atoms will later combine with to form water. I hope I helped give insight from my understanding. I'm only 15 and in grade 11 so I hope I made sense. Seeing that your question was asked 5 months ago, if you got the answer to it please help me understand as well. Thank you.
maybe with a couple of solar cells in the system you can not perpetuate but extend the life of it, even thinking about a car with the wind energy of the movement you could even extend the life of the cell a little further
I understand the separation and movement of the electrons but how are you capturing the energy from their movement. What sort of "work" are they doing during their movement ? Running a generator ? Powering an electrical device directly ?
I have seen multiple sometimes conflicting accounts of the dimensional size of an electron. While I cannot verify these data, some report the electron to be roughly 4 times the diameter of the proton. If this is correct? If not, I would be interested to know the proper values.
Hello there!!! Thanks for sharing bro..I have a question for you:- I know that the electrolyte made of Polymer membrane sheets, but where can I find them in our daily life or at home, appliances?, and the same for catalyst.. what they look like what they are made of???please give examples of show pictures. Thanks in advance.
Yup, you're exactly right. Electrons are indeed much smaller than protons. It's not a perfect analogy, but I'm just trying to get the very basic concepts across right here. In reality, it's not about size--it's about charge, but I couldn't come up with a good analogy for that. In a fuel cell, that "camp fence" is actually a special membrane that allows positively charged things to pass through, but not negatively charged things. So protons can go right through, but elections cannot.
Would it then be possible to separate the water into hydrogen and oxygen molecules again, sending them back to their respective "camps", and creating a self perpetuating and sustaining energy source?

Jennifer Flores, I agree infinitely.
yes...but its a bit weird to be honest though
@@whiteeyedshadow8423 why is it wierd? It's true.
mostly high school, 9-12 grade. but also sometimes middle school.
even a guy with IQ 10 could understand your description!! congrats Tyler.

I paused the video to laugh about the metaphor lol. You're awesome! Well done.
Finally someone that can actually teach!!
You are one of the most talented and genius teachers. You have expertise to make the hardest topic very easy. This video is no less than masterpiece from your side. Love you ,Sir.
You really deserved to be called Sir. ❤
very interesting! I don't think I'll ever forget this! and thankyou this helped alot!
No one better than you can teach this topic
Very simple, creative and easy to understand explanation of how fuel cell work. Thank you.

YAYYYYY!!! I WILL BE ABLE TO DO GOOD IN MY EXAMS NOWWWWWWWWW. every topic i search, have your videos. Omg. I dont have words to thank u.
problem with this guy is that he puts all other teacher to shame...
i guess someone has to be the best...
Don't change the format of your videos. That's what drew me to them. Your talking to both sides of our brains at once "Brilliant ".
David A. Puchta
Brilliant, Sir! That's how education should be done.
This teaches me something while im on my brake. Great Job Sir.
The best teach I've ever seen
Thanks for simple demonstration of fuel cell.
your videos are so easy to understand. you made chemistry my favorite subject. thanks. why don't you make more video?
Great help. Fully understood what i confused about in class. Thank you.
Loved the way u explained🥰🥰👍👍👍
Thanks so much for explaining that. Your are the only one so far speaking of these all important details - and the Catalyst !!.

Quite enriching video Tyler. Keep it up
Thank you so much for this tutorial! I have oomph for my Chemistry exam next week!
Amazing Sir...Best explanation of Hydrogen fuel cell...😊
Nice video! Thanks! Wasn't over keen on the analogy but helped my understanding anyway!
you know what, this is incredibly awesome!
When the protons and the electrons are separated, the electrons gain electrical potential energy. The electrical device is placed along the electrons' path to be activated when the electrons pass through.
Very nice video. You cleared up a lot of my questions. One other question, what sort of catalyst could decompose a hydrogen atom?
I love the way you teaching , your video is really useful and understand
Thanks for your video
clever analogy, well done sir!
Damn, you did it again. I think you got a lot going on in your head with summer camp teens.
Hey there thanks so much for the efforts u put in remaking the video

+Juliet i think u might be right can u expl;ain me briefly..?
This is awesome! I'm going to go build a fuel cell now!
Very good explanation, thanks!
Mr Tyler, that was a brilliant analogy , Thankyou😁😁😁😁😆
Great analogy well done, great help
Nice explanation and comparation.
That was a wonderful explanation! I was wondering if you could give me an analogy for the salt bridge though?
Super super easy explaining!! Thx!

I love ur vid. Awesome demo and great demonstration XD more plz
Please make a video on photoelectrochemical cell and water splitting which are the now a days emerging issues and a solution to green energy
We all know what tyler got up to at camp ;)
maybe with a couple of solar cells in the system you can not perpetuate but extend the life of it, even thinking about a car with the wind energy of the movement you could even extend the life of the cell a little further
Very good explanation. However i do not really understand why is the oxygen needed on the right hand side ?
I understand the separation and movement of the electrons but how are you capturing the energy from their movement. What sort of "work" are they doing during their movement ? Running a generator ? Powering an electrical device directly ?
God bless u Tylerrrrrr!
haha you took the metaphor too far hehe, but it made me understand, thanks hehee

for an assignement on school i was thinking of making a fuel cell but instead of platina would i be able to use sulfuric acid as electrolyte
thanks
At 3:57 - electrons like "chunky kids"? but aren't they actually wayyyyyyyy smaller than protons?

Do you have a video that solely deals with electronegativity and covalent bonds?
well said
you should teach our science class!

Can i ask will you be posting new teaching lessons here in youtube?
