摘要: A Polymer Electrolyte Membrane is formed by hot air drying of a membrane formed with an acidic main-polymer having proton conductivity and capability of forming an electrolyte membrane (S12), and then immersing it into a basic polymer solution to impregnate the membrane with the basic polymer (S14). The basic polymer is introduced in a large quantity into a site acting as a proton conduction pass of the main-polymer to take charge of the proton conduction. Since in the Polymer Electrolyte Membrane, a base polymer takes charge of proton conduction as compared with the case where proton takes charge of the proton conduction as a hydrate, the base polymer shows favorable proton conductivity even in a low humidity state at an elevated temperature exceeding boiling point of water.

摘要: A fuel cell is disclosed comprising: a power generation layer including an electrolyte membrane, and an anode and a cathode provided on respective surfaces of the electrolyte membrane; a fuel gas flow path layer located on a side of the anode of the power generation layer to supply a fuel gas to the anode while flowing the fuel gas along a flow direction of the fuel gas approximately orthogonal to a stacking direction in which respective layers of the fuel cell are stacked; and an oxidizing gas flow path layer located on a side of the cathode of the power generation layer to supply an oxidizing gas to the cathode while flowing the oxidizing gas along a flow direction of the oxidizing gas opposed to the flow direction of the fuel gas. A power generation area of the fuel cell, in which electric power is generated, has an upstream region including a most upstream position along the flow direction of the fuel gas and a downstream region including a most downstream position along the flow direction of the fuel gas. A midstream region, which is a remaining region of the power generation area other than the upstream region and the downstream region, has higher water vapor transfer resistance between the anode side and the cathode side than the upstream region and the downstream region.

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.
