A fuel cell catalyst containing platinum, zinc, and at least one of nickel and iron.

Fuel cell electrocatalyst of Pt-Zn-Ni/Fe

An improved metal alloy composition for a fuel cell catalyst containing platinum, manganese, and cobalt.

Fuel cell electrocatalyst of Pt-Mn-Co

An improved metal alloy fuel cell electrocatalyst composition containing platinum, rhodium, molybdenum, and nickel iron or a combination thereof.

Fuel cell electrocatalyst of Pt-Rh-Mo-Ni/Fe

A fuel cell provides a high output at a high current density. The fuel cell has an anode electrode and a cathode electrode comprising a gas diffusion layer, a water-repellent layer disposed on the gas diffusion layer and containing a carbon material and polytetrafluoroethylene, and an electrode catalyst layer disposed on the water-repellent layer and containing a carbon material carrying a catalyst. The electrode catalyst layer has maximum and minimum thicknesses that differ from each other by less than 30 &#x3bc;m. The electrode catalyst layer has cracks whose area is less than 10% of a total area of the electrode catalyst layer.

Electrode for fuel cell, method of manufacturing same, and fuel cell with such electrode

An electrode base material is held by electrostatic attraction when a voltage from a DC power source is applied to electrodes for electrostatic attraction. A paste is applied to the electrode base material, and then the paste is dried to form the water-repellent layer. Subsequently, another paste is applied to the water-repellent layer, and then the paste is dried. Accordingly, the substantially flat electrode catalyst layer including an extremely small number of depressions is formed. The electrode of the fuel cell produced as described above can be used as an anode or a cathode.

Method of and apparatus for producing electrode of fuel cell

This invention provides an electrode for a fuel cell comprising a catalyst layer obtained by a first step of homogeneously mixing carbon supporting platinum which is an electrode catalyst, an alcohol solution of an ion conductive component which is a solid polymer electrolytic membrane component, and an organic solvent, by means of a stirrer having a grinding effect to produce electrode paste in which the carbon is highly dispersed; a second step of stirring said electrode paste by means of a three-dimensional vibrating stirrer in order to obtain highly structured carbon on which platinum is supported; and a third step of coating a gas diffusion electrode material and/or a solid polymer electrolytic membrane with the electrode paste in which the carbon is highly structured, followed by removal of the organic solvent.
