Abstract

Proton exchange membrane fuel cell cathodes require new designs to reduce Pt content effectively. Here, Dull et al. introduce a bottom-up electrode fabrication architecture to study and optimize the catalyst microstructure. It is found that cathodes prepared with mesoporous furnace carbons and agglomerated ionomer dispersions deliver a notable fuel cell performance.
