FUEL CELL ANODE CATALYST AND MANUFACTURING METHOD THEREFOR |
摘要 |
Provided is a fuel cell anode catalyst in which a platinum-ruthenium alloy is supported on a carbon material, and a manufacturing method therefor. The molar ratio (Pt:Ru) of the alloy is in the range of 1:1-5. When the coordination numbers of the Pt atom and the Ru atom of an atom site in the alloy, as measured by x-ray absorption fine structure, are expressed as N(Pt) and N(Ru) respectively, then N(Ru)/(N(Pt)+N(Ru)) in the platinum site is in the range of 0.8-1.1 times the theoretical value, and N(Pt)/(N(Ru)+N(Pt)) in the Ru site is in the range of 0.8-1.1 times the theoretical value. The average particle diameter of the alloy is in the range of 1-5 nm, and the standard deviation for the grain size is in the range of 2 nm or lower. Further provided is: a fuel cell anode with an anode composition layer, on a substrate surface, which contains the catalyst and a proton conductive polymer; a fuel cell membrane electrode assembly with a polymer electrolyte membrane sandwiched between the anode and a cathode; and a fuel cell containing the fuel cell membrane electrode assembly. |
