    摘要： Disclosed is a separator for fuel cells which is decreased in the amount of an expensive noble metal used as a raw material while being maintained to be conductive to the MEA. This separator has durability and corrosion resistance to very corrosive substances such as fluorine ions or hydrofluoric acid. Also disclosed is a method for producing such a separator for fuel cells. Specifically disclosed is a metal separator (15, 17) which is used in a polymer electrolyte fuel cell using a fluorine-containing polymer electrolyte membrane. This metal separator (15, 17) comprises a stainless steel base (20) processed to have a plurality of fuel gas channels (14). A pure Ti layer (21) is formed on the surface of the base (20); a Pd layer (23) is formed on a surface of the pure Ti layer (21) on the side of the fluorine-containing polymer electrolyte membrane; and a composite metal layer (22) is made of the pure Ti layer (21) and the Pd layer (23) by alloying at least a part of the Pd layer (23) joined with the surface of the pure Ti layer (21) through a heat treatment.

    摘要： A current-collecting composite plate for a fuel cell configured with unit cells according to the present invention, which comprises: an insulator layer; and a plurality of pairs of conductor layers, the conductor layers being bonded to the insulator layer to be spaced apart from each other by a predetermined distance, each pair being used for adjacently disposed anode and cathode electrodes for a different one of the unit cells by sandwiching an electrolyte assembly therebetween. And, each conductor layer includes: a first conductor layer of a corrosion resistant metal treated with an electrically conductive surface treatment; a second conductor layer of a metal with low electrical resistivity; a through-hole penetrating the first conductor layer and the insulator layer; and a connecting portion formed of the second conductor layer for connecting the unit cells.

    摘要： A metal separator for fuel cells formed with a metal plate and provided between cells accumulated, in which the metal plate is formed like trapezoidal irregularities to separate channels for a fuel gas from ones for an oxidant gas. Slope portions are formed after forming uniformly and thinly wall thickness of both upper and lower flat portions or either of the upper or the lower flat portion to 90% or less of that of the metal plate to be formed to obtain trapezoidal irregularities by forming flat portions which contact upper and lower cells and slope portions which interconnect the upper and the lower flat portions.
