Advance in Electrocatalysts for Polymer Electrolyte Membrane Fuel Cells

Electrocatalyst is the significant sub-assembly in fuel cells as well as the key to reduce the cost of fuel cells.In this paper,the domestic and foreign research advances in the electrocatelysts for polymer electrolyte membrane fuel cells(PEMFCs)and direct methanol fuel cells(DMFCs)in recent years,with the emphasis of catalyzing mechanism,are re- viewed.
