Abstract
Official abstract text for this publication.
A production method of a fuel cell electrode catalyst includes: a supporting step of causing platinum and yttrium to be supported on a carrier using a nonaqueous solvent; and an acid treatment step of performing an acid treatment on the carrier on which platinum and yttrium are supported.
First claim
Opening claim text (preview).
What is claimed is: 1. A production method of a fuel cell electrode catalyst, comprising: causing platinum and yttrium to be supported on a carrier using a nonaqueous solvent; and performing an acid treatment on the carrier on which platinum and yttrium are supported. 2. The production method according to claim 1 , wherein platinum and yttrium are supported on the carrier by mixing the nonaqueous solvent, a platinum salt, an yttrium salt, and the carrier and irradiating a mixture of the nonaqueous solvent, platinum, yttrium, and the carrier with microwaves. 3. The production method according to claim 1 , wherein platinum and yttrium are supported on the carrier by mixing the nonaqueous solvent, a platinum salt, an yttrium salt, and the carrier, removing the nonaqueous solvent from a mixture of the nonaqueous solvent, platinum, yttrium, and the carrier, and performing a heat treatment on the mixture from which the nonaqueous solvent is removed in a hydrogen atmosphere. 4. The production method according to claim 1 , wherein an atomic ratio of platinum to yttrium in the fuel cell electrode catalyst is caused to be 100 to 250 by performing the acid treatment on the carrier on which platinum and yttrium are supported. 5. A fuel cell electrode catalyst produced by the production method according to claim 1 . 6. A fuel cell comprising the fuel cell electrode catalyst according to claim 5 .
