Abstract

Official abstract text for this publication.

An alkaline fuel cell electrode catalyst includes a first catalyst particle that contains at least one of iron (Fe), cobalt (Co) and nickel (Ni), a second catalyst particle that contains at least one of platinum (Pt) and ruthenium (Ru), and a carrier for supporting the first catalyst particle and the second catalyst particle.

First claim

Opening claim text (preview).

The invention claimed is: 1. An alkaline fuel cell electrode catalyst comprising two kinds of catalyst particles: a first catalyst particle being a Fe—Co—Ni particle, and a second catalyst particle being a Pt—Ru particle, wherein each of the first catalyst particle and each of the second catalyst particle are directly supported on a single carrier, wherein the carrier is a carbon powder carrier and is composed of particles of 30 nm to 100 nm in particle size.…
