CATALYST FOR POLYMER SOLID ELECTROLYTE FUEL CELL, MEMBRANE ELECTRODE ASSEMBLY, AND FUEL CELL
摘要：
There is provided a catalyst for a fuel cell, which simultaneously realizes excellent catalytic activity and catalytic stability. The catalyst for a fuel cell comprises a fine particle of a metal represented by formula: PtxRuySizT1u wherein T1 represents at least one element selected from the group consisting of nickel (Ni), tungsten (W), vanadium (V), and molybdenum (Mo); x=30 to 90 atomic %; y=0 to 50 atomic %; z=0.5 to 20 atomic %; and u=0.5 to 40 atomic %, or comprises a fine particle of a metal represented by formula: PtxRuySizT2u wherein T2 represents at least one element selected from the group consisting of hafnium (Hf), tin (Sn), zirconium (Zr), niobium (Nb), titanium (Ti), tantalum (Ta), chromium (Cr), and aluminum (Al); x=30 to 90 atomic %; y=0 to 50 atomic %; z=0.5 to 20 atomic %; and u=0.5 to 40 atomic %.
