Abstract

A liquid cooled bipolar separator plate assembly for use in the construction of a fuel cell, is described. The bipolar separator plate assembly comprises a pair of rectangular perforated distributor plates disposed in spaced parallel relationship by an intermediate structure. This structure may be comprised of two separated plates (12,12') of undulated cross-section with each plate defining longitudinal peaks and valleys. The separator plates are also rectangular plates and are interconnected in back-to-back relationship at the peaks (13) to form a group of inner adjacent cooling liquid channels (15) therebetween and a first and second group of outer gas channels (16,17) on opposed outer sides of the interconnected separator plates. The peaks on the outer sides are secured to a respective one of the perforated distributor plates (11,11'). The perforated distributor plates and separator plates are sealingly secured together along their opposed side edges. The inner cooling liquid channels and the outer gas channels are opened at opposed end edges of the interconnected separator and distributor plates. An end manifold (25)is sealingly secured to each of the opposed end edges. The end manifolds each have interconnecting conduits to interconnect the cooling liquid channels together and the first and second groups of gas channels, respectively, together.
