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

A method for evaluating the performance of an electrode catalyst for a fuel cell having a catalyst metal supported on a conductive support, wherein a voltammogram area/catalyst specific surface area of the electrode catalyst is used as an index for the performance evaluation, and the performance is evaluated as good when the voltammogram area/catalyst specific surface area is 1.0×10 -4 (mV·A·g/m 2 ) or more. The object is to develop a technique for accurately evaluating the performance of an electrode catalyst for a fuel cell, as well as to search for an electrode catalyst for a fuel cell having excellent performance, and further, to specifically obtain a novel electrode catalyst for a fuel cell having excellent catalyst activity which was searched for using this technique.
