SEPARATOR FOR FLAT TYPE POLYELECTROLYTE FUEL CELL AND POLYELECTROLYTE FUEL CELL EMPLOYING THAT SEPARATOR

摘要

A separator for flat type polyelectrolyte fuel cell, and a polyelectrolyte fuel cell employing that separator. In recent years, the fuel cell has been required to be made as thin as possible and the separator has been required to be made as light as possible while ensuring the strength and to have a sealing function. The separator comprises a separator member coupling body having a metal plate as a basic body and formed by integrally coupling a plurality of separator members provided with a plurality of fuel supply trough holes arranged orthogonally to the surface of the basic body in association with unit cells, and a frame coupling body of insulating material formed by integrally coupling a plurality of frame parts for insulating the unit cells from each other and provided with a fuel supply opening corresponding to each separator member, wherein the frame coupling bodies are paired to clamp the separator member coupling body and each frame part of one frame coupling body can be fitted, in the opening thereof, with the composite membrane electrode of the fuel cell.
