FUEL-CELL ELECTRODE CATALYST, AND PRODUCTION METHOD THEREFOR

摘要

An object of the present invention is to provide a fuel-cell electrode catalyst in which a catalyst metal is uniformly supported on a support. This object can be achieved by a fuel-cell electrode catalyst comprising a support having pores and a catalyst metal uniformly supported on the support, wherein at least 80% of the support has a primary particle size within ± 75 % of the mean primary particle size of the support.
