Surface Treatment of Pt Cathode Using Ceria Infiltration for High Performance Polymer Electrolyte Membrane Fuel Cells

This study evaluates the performance and stability of Pt cathodes, which are treated by infiltrating cerium oxide (CeOx) onto their surfaces, in polymer electrolyte membrane fuel cells. The concentration of CeOx on the surface of Pt is adjusted by varying the concentration of the cerium precursor in...
