MULTILAYER FUEL CELL ELECTRODE SUBSTRATE HAVING ELONGATED HOLES FOR FEEDING REACTANT GASES

摘要

TITLE OF THE INVENTION: MULTILAYER FUEL CELL ELECTRODE SUBSTRATE HAVING ELONGATED HOLES FOR FEEDING REACTANT GASES A carbonaceous multilayer electrode substrate for a fuel cell disclosed herein has elongated holes for feeding reactant gases to the fuel cell. The electrode substrate comprises at least one porous carbonaceous layer having such holes. An electrode substrate of the invention comprises such a porous layer and a dense layer capable of effecting a function as a separator sheet. An another substrate of the invention comprises a dense layer and two such porous layers on both surfaces of the dense layer. A still another substrate comprises an extended dense layer and two such porous layers on both surfaces of the dense layer.
