Abstract: The invention relates to a method for fabricating porous carbon articles. In accordance with the invention, the method comprises the steps of coating chopped carbon fibers with a low viscosity mixture of at least 70% by weight furfuryl alcohol, 0.25 - 5%,by weight, of an aqueous solution of 85% phosphoric acid or an equivalent amount of phosphoric acid, and a balance of water. A mat of coated fibers is then formed, and the furfuryl alcohol is polymerized and the mat is cured by heating the mat to a temperature between 50.degree. - 200.degree.C. The cured mat is carbonized by heating to at least 1500.degree.C. in either an inert atmosphere or a vacuum.

Abstract: CARBON FOAM FUEL CELL COMPONENTS In an electrochemical cell, such as a fuel cell, the gas distribution layer, which is the layer of material disposed directly behind and contiguous with the catalyst layer, is made from gas porous open cell carbon foam. Vitreous carbon foam is preferred. Vitreous carbon foam is extremely corrosion resistant to many of the very reactive chemicals which might be used as an electrolyte in a fuel cell, such as phosphoric acid. It also has low electrical resistivity, good thermal conductivity, and can be made very thin and inexpensively. Preferably the cell catalyst layer is applied directly to one surface of the foam layer.
