Patent

CA 2423339

An electro-chemical device having a high catalyst utilization efficiency includes a gas diffusion electrode formed of a carbonaceous material and having a catalyst formed on at least a portion of its surface, and an electrolyte film provided in contact with one surface of the gas diffusion electrode. The amount of the catalyst formed on the portion of the carbonaceous material contacting with the electrolyte film is lesser on the side electrolyte film than on the side opposite to the electrolyte film. So, the catalyst utilization efficiency is increased appreciably to render it possible to elevate the energy efficiency of the electro-chemical device.

La présente invention concerne un dispositif électrochimique, comportant des électrodes réalisées en matériau carboné présentant un catalyseur formé au moins en partie à la surface de celles-ci et une membrane électrolytique formée en contact avec une surface latérale des électrodes à diffusion de gaz, dans laquelle la quantité de catalyseur formé à la partie du matériau carboné en contact avec la membrane électrolytique est rendu inférieure sur le côté de la membrane électrolytique à la quantité sur le côté opposé au côté de la membrane électrolytique, produisant ainsi une nette amélioration du rendement du catalyseur et de la performance énergétique du dispositif électrochimique.
