Abstract

PURPOSE:To produce an electrode having holes of equal size and good durability with an excellent yield by employing in an fuel cell/electrode, a layer with small holes, which is made by piling foils having holes, adhering one another and sintering them. CONSTITUTION:A foil 9 is prepared by feeding carbonyl nickel powder 10 in holes provided on a 15mu thick nickel foil by an etcking method, followed by sintering. A 8mu thick foil 11 having holes is piled thereon. Further, a 15mu thick foil 12 with holes is piled on it. Three foils are correctly piled and spot-welded at each point. More than 10 scores of them are further stacked, inserting a tantalum plate between then so as not to be mutually sintered. Thus prepared pile group is inserted between iron plates. The iron plates are sintered at 1,000 deg.C, in an argon atmosphere for 1hr, and lightly pressed from both sides to obtain a fine porous layer.
