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

A first gas diffusion layer for constructing an anode electrode and a second gas diffusion layer for constructing a cathode electrode are provided with first and second gas flow passages which are formed opposingly to first and second flow passages provided on first and second separators respectively. A fuel gas is supplied to the first flow passage and the first gas flow passage, while an oxygen-containing gas is supplied to the second flow passage and the second gas flow passage. Accordingly, the fuel gas and the oxygen-containing gas are uniformly diffused and supplied to first and second electrode catalyst layers respectively.

Fuel cell with gas diffusion layer flow passage

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.

Electrodes for fuel cells

A shaped-article for use in producing a fiber-reinforced composite member is formed of short fibers and deformed fibers. The deformed fibers have a plurality of needle-like portions extending from a nucleus portion. The short fibers are orientated at random by dispersing the deformed fibers. The fiber shaped-article is formed by pouring a slurry of the short fibers and deformed fibers dispensed in a liquid into a mold, compressing the slurry and removing the liquid.
