Pd−Co−Mo Electrocatalyst for the Oxygen Reduction Reaction in Proton Exchange Membrane Fuel Cells

“…However, platinum is expensive and the limited world's supply of platinum poses serious problems for a widespread commercialization of the fuel cell technology. These difficulties have created enormous interest in the search for less expensive, more efficient electrocatalysts as well as in lowering the catalyst loading. − With respect to identifying alternative electrocatalysts, non-platinum based metal combinations, − metal oxides, − carbides, chalcogenides, , enzymes, , inorganic and organometallic complexes, , and porphyrins have been investigated over the years for ORR, but they generally exhibit lower catalytic activity than Pt.…”
