CA 2510068

A solid heteropolyacid catalyst for a fuel cell, which comprises a partial salt of a heteropolyacid comprising a noble metal and/or a transition metal and having a molecular weight of 800 to 10000; and an electrode using the solid heteropolyacid catalyst. The solid heteropolyacid catalyst exhibits greatly excellent durability against a poisoning gas such as CO and thus provides a high performance capability catalyst for a direct methanol type fuel cell which uses methanol as a fuel.

L'invention concerne un catalyseur hétéropolyacide solide pour pile à combustible comprenant un sel partiel d'hétéropolyacide, qui renferme un métal noble et/ou un métal de transition et qui possède un poids moléculaire compris entre 800 et 10 000; et une électrode utilisant ledit catalyseur hétéropolyacide solide. Le catalyseur possède une excellente durabilité contre un gaz d'empoisonnement tel que le CO, ce qui confère une capacité de performance élevée a à un catalyseur de pile à combustible du type méthanol.
