    摘要: In a polymer electrolyte membrane type fuel cell employing a high polymer ion exchange membrane as an electrolyte, a fuel cells stack is produced at a low cost by easily constituting flow passages for a fuel gas, an oxidizing agent gas and a cooling water which have been conventionally constituted by a cutting process being hard to process and hard to reduce a cost. The fuel gas passage, the oxidizing agent gas flow passage and the cooling water flow passage are constructed by a combination of a diffuser constituted by a conductive porous body or a corrugated plate and an elastic gasket, whereby a cutting process is not required, and a number of parts can be reduced and an operating performance can be improved by integrally forming the gasket with the separator, so that a cost can be reduced.

    摘要: A fuel cell apparatus of a compact size uses a hydrogen storage alloy, in which heat can be efficiently transmitted from fuel cell bodies to the hydrogen storage alloy. The fuel cell apparatus includes a plurality of fuel cell bodies, a hydrogen storage tank, a hydrogen supply device for supplying hydrogen to the fuel cell bodies from the hydrogen storage tank, an air feed device for supplying the air, supplying oxygen, a secondary battery, and a casing receiving the above components therein which casing has air intake ports and an air discharge port for the air feed device, and is formed as to enable the hydrogen storage tank to be introduced into and removed from the casing. The hydrogen storage tank is disposed on that side surface of each of at least one pair of fuel cell bodies, facing away from a cathode thereof, through a heat transmission device. With this construction, the energy of heat, generated by the fuel cell bodies, is efficiently transmitted to the hydrogen storage tank, and the stable supply of the hydrogen can be achieved, and the whole of the power system can be formed into a compact design.

    摘要: A polymer electrolyte fuel cell comprises an electrolyte membrane-electrode assembly, a pair of conductive separator plates sandwiching the electrolyte membrane of the electrolyte membrane-electrode assembly, and a pair of sealing means sealing between the electrodes of the electrolyte membrane-electrode assembly and the separator plates. The pair of sealing means is constituted by combination of a flat sealing member having a flat portion in flat contact with the electrolyte membrane and of a linear sealing member having a rib in linear contact with the electrolyte membrane, and at least part of the rib is in the form of falling in the direction to the electrode when the electrolyte membrane, the pair of electrodes and the pair of separator plates are stacked to be cramped. This makes it possible for the fuel cell to have an excellent sealing property and a stable output characteristic.
