    摘要： A polymer electrolyte fuel cell stack that includes a cell laminate having a plurality of unit cells, which are laid one upon another and each of which includes a polymer electrolyte membrane, a pair of electrodes arranged across the polymer electrolyte membrane and having respective catalytic reaction layers, a separator having means for feeding a supply of fuel gas containing hydrogen gas to one of the electrodes, another separator having means for feeding a supply of oxidant gas to the other of the electrodes, and a manifold for feeding the supply of fuel gas or the supply of oxidant gas to the respective electrode and disposed on a side face of each unit cell. In the polymer electrolyte fuel cell stack, a sealing portion is disposed at least in the vicinity of each electrode. The polymer electrolyte fuel cell stack has excellent durability and productivity. Gasket sealing portions, a sealing portion for cooling water, and sealing portions for water and gas in an internal humidifying unit are composed of a polymer compound that has polyisobutylene as the backbone structure. This arrangement ensures high reliability.

    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.
