Screen Printing - the Green Skills for Hydrogen Lab Series

With the Green Skills for Hydrogen Lab Series, we want to make the core technologies of the green #hydrogen economy tangible: You are invited into the laboratories where electrolysis cells and fuel cells are fabricated using state-of-the-art processes, testing, and development.
In this video you see steps in the process of “screen printing”: A technique used to make layers for SOFC/SOEC (Solid Oxide Fuel Cell/Solid Oxide Electrolysis Cell), for example electrode layers.
Screen printing for SOFC/SOEC involves applying functional ceramic inks onto substrates through a patterned mesh screen.
The inks, made from ceramic powders, binders, and solvents, are spread using a squeegee, forming precise layers.
The process includes preparing the screen with a stencil pattern, printing the ink onto the substrate, and then drying and sintering the printed layers.
This method allows for the accurate and uniform deposition of thin, well-defined layers, essential for the high performance and efficiency of SOFCs and SOECs.

The video is exemplary, which means it does not cover all the steps of the process but selected, important ones. The scale of production presented mimics research needs, but the core techniques are basically the same as in industrial production.
