    摘要： A polymer-electrolyte fuel cell having: an electrolyte membrane-electrode assembly having a polymer-electrolyte membrane and a pair of gas-diffusion electrodes sandwiching the polymer-electrolyte membrane; a first electroconductive separator having a gas channel for supplying an oxidant gas to one of the gas-diffusion electrodes of said pair; and a second electroconductive separator having a gas channel for supplying a fuel gas to the other of the gas-diffusion electrodes of the pair. The polymer-electrolyte fuel cell is characterized in that: at least one of the first and second electroconductive separators has a metal substrate and an electroconductive resin layer on the substrate and contacting the electrolyte membrane-electrode assembly; and the electroconductive resin layer has a resin having water-repellant or basic radicals, and an electroconductive particulate substance which has a carbon powder of a specific surface area of less than 100 m2/g.

    摘要： The present invention provides a fuel cell stack including a plurality of unit cells laid one upon another. Each of the unit cells includes an electrolyte, a pair of electrodes that are arranged across the electrolyte and respectively have a catalytic reaction layer, and a separator having means for feeding a supply of gaseous fuel to one of the electrodes and a supply of oxidant gas to the other of the electrodes. The separator is a laminate including a gas-tight conductive plate A and another conductive plate B having at least one slit, which continuously meanders from one end to another end of the conductive plate B. The technique of the present invention gives a compact fuel cell stack assembled by a simple process.

    摘要： The present invention provides a polymer electrolyte fuel cell having a small-sized, light-weighted mechanism for fastening a stack of unit cells assembly. The polymer electrolyte fuel cell of the present invention includes a stack of unit cells obtained by laying a plurality of unit cells one upon another; a first end plate disposed on one end of the stack of unit cells; a second end plate arranged on the other end of the stack of unit cells; an auxiliary plate disposed at least outside the first end plate; at least one set of restraining means, each of which has a band-like shape and restrains a first member located on one end of an assembly, which includes the stack of unit cells, the first and the second end plates, and the auxiliary plate, and a second member located on the other end of the assembly to restrict separation of the first member and the second member from each other; a screw fitted in a threaded hole formed in the auxiliary plate in such a manner that an end of the screw comes into contact with the first end plate; and compressive means that generates a repulsive force to compress the stack of unit cells when the screw is fitted in the threaded hole of the auxiliary plate.
