    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.

    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 device, wherein, after an output voltage from a main body of a fuel cell is converted using a converter, the relation between the resultant predetermined output voltage V 1 and an output voltage V 2 from a secondary battery is so set as to satisfy V 1>V 2. When, at the time of a sudden change of an external load, the output voltage V from the main body of the fuel cell becomes lower than a predetermined voltage V 3, an output to a charge controlling unit is stopped. When the output voltage V from the main body of the fuel cell is lowered even further and becomes lower than a predetermined voltage V 4, an output to an auxiliary device, which is necessary for driving the fuel cell device, is switched from the output from the converter to the output from the secondary battery.
