[Materials] Low voltage SEM-EDX of a Fuel Cell Catalyst

A fuel cell catalyst was observed at the landing voltage of 300 V using beam deceleration. While the SE image visualized the aggregated structure of the carbon supports with topographic information, the BSE image showed a striking contrast between areas with compositional insight. Subsequent EDX analysis suggested the compositional difference between the carbon supports and the ionomer.
