SUPPORTED CATALYST FOR FUEL CELL AND PROCESS FOR PRODUCTION THEREOF, AND FUEL CELL

摘要

An object of the present invention is to provide a supported catalyst for a fuel cell having a high activity, a method of manufacturing thereof, and a fuel cell including the supported catalyst for a fuel cell. A supported catalyst for a fuel cell of the present invention includes a conductive carrier and catalyst particle supported on the conductive carrier and contains platinum, an oxygen concentration in the catalyst particle measured by using an inert gas fusion-nondispersive infrared absorption method being reduced to 4 mass% or less.
