专利汇可以提供Low temperature fuel battery专利检索,专利查询,专利分析的服务。并且PURPOSE: To provide a low temperature fuel battery hating excellent initial properties and reliability by controlling the choking of an electrode catalyst layer by an electrolyte.
CONSTITUTION: An oxidizing agent gas is led along one main side of an electrode substrate 1 and an electrode catalyst layer 5 is layered on the other main side to diffuse the gas in the electrode catalyst layer 5 and fluoro-resin 8 concentration is gradually increased toward the direction from one end in the layered plane where the oxygen concentration in the gas becomes the maximum to the other end of the layered plane where the oxygen concentration becomes the minimum. Also, the specific surface area of carbon black 7 is decreased in the layered plane of the electrode catalyst layer 5 toward the direction from one end of the layered plane where the oxygen concentration in the gas becomes the maximum to the other end of the layered plane where the oxygen concentration becomes the minimum, so that the catalyst layer 5 is prevented from being choked up by an electrolyte.
