摘要： An object of the present invention is to provide a production method which can increase the activity of a catalyst particle comprising a core particle and an outermost layer, the core particle comprising at least one of palladium and a palladium alloy, and the outermost layer comprising at least one of platinum and a platinum alloy and covering the core particle. Disclosed is a method for producing a catalyst for fuel cells, in which a catalyst particle is supported by an electroconductive carrier, the method comprising the steps of: preparing a supported catalyst in which a catalyst particle comprising a core particle and an outermost layer is supported by an electroconductive carrier, the core particle comprising at least one of palladium and a palladium alloy, and the outermost layer comprising at least one of platinum and a platinum alloy and covering the core particle; acid treatment to bring the supported catalyst into contact with an acid solution which dissolves palladium more preferentially than platinum; and firing the supported catalyst at 80°C or more and less than 200°C in a reducing gas atmosphere after the acid treatment step.

摘要： The present invention provides a catalyst layer for fuel cells having improved characteristics and a production method therefor.
A catalyst layer for a fuel cell, including a carbon carrier having pores, a catalyst metal carried on the carbon carrier, and an ionomer covering the carbon carrier, wherein the crystal length of the carbon carrier is not less than 6 nm, and the coverage of the catalyst metal by the ionomer is 55% to 65%, and a method for the production of a catalyst layer for a fuel cell, including heat-treating a carbon carrier having pores under an inert gas atmosphere so that the crystal length of the carbon carrier becomes not less than 6 nm, heat-treating the heat-treated carbon carrier under an oxygen atmosphere to activate the carbon carrier, allowing the activated carbon carrier to carry a catalyst metal, mixing the carbon carrier carrying the catalyst metal and an ionomer to cover the carbon carrier with the ionomer, and forming the catalyst layer for a fuel cell using the carbon carrier covered with the ionomer.
