METHOD FOR EVALUATING PERFORMANCE OF ELECTRODE CATALYST FOR BATTERY, METHOD FOR EXPLORING ELECTRODE CATALYST FOR BATTERY, ELECTRODE CATALYST FOR BATTERY, AND FUEL BATTERY USING THE ELECTRODE CATALYST

摘要

This invention provides a method for evaluating the performance of an electrode catalyst for a fuel battery, comprising a catalyst metal supported on an electroconductive carrier. In the evaluation method, the value of voltammogram area/catalyst specific surface area in the electrode catalyst is used as an index for performance evaluation, and, when the value of voltammogram area/catalyst specific surface area is not less than 1.0×10-4(mV A g/m2), the performance is evaluated as good. According to this constitution, the performance of the electrode catalyst for a fuel battery can be properly evaluated. There are also provided a method for exploring an electrode catalyst for a fuel battery, having an excellent performance, and a novel electrode catalyst for a fuel battery, having an excellent catalytic activity, explored by the above method.
