Design of Interfaces and Phase Interfaces on Cathode Catalysts for Polymer Electrolyte Fuel Cells

Development of heterogeneous catalysts for energy conversion has been required to solve environmental issues arising from the combustion fossil fuels. Polymer electrolyte fuel cells (PEFC) are promising power generation devices alternative internal engine. PEFC performance is strongly dependent on catalytic activity oxygen reduction reaction at cathode because sluggish kinetics. Thus, highly active and durable Pt-based with tailored geometrical electronic structures have widely developed. The used in membrane-electrode-assembly (MEA) PEFC, where catalyst particles integrated as layers a few micrometers thick. Porous structure morphology nanometer micrometer scale should be designed facile diffusion oxygen, proton water. In this highlight review, we provide an overview development high durability PEFC. one devices. Highly
