Abstract

A fuel cell assembly has thermoplastic bipolar plates sandwiched between a number of electrode assemblies (30, 30') to form a stack. A bipolar plate (35) alternates with an electrode assembly (30) so that one side (31)of the plate is adjacent and adhesively bonded to the corresponding surface of one electrode assembly anode (34), and the other side (39) is adjacent and adhesively bonded to the corresponding surface of a cathode (32) in the neighboring electrode assembly (30'). The adhesive bonding also serves to seal the fuel and oxidant channels (37).
