Abstract: A fuel cell bipolar plate assembly is disclosed which includes a reinforcement positioned between the anode and cathode plates to strengthen the assembly.

Abstract: A fuel cell unit incorporates a pair of plates; one plate an anode, the other a cathode. Respective anode and cathode plates are physically bonded together to form such pairs; wherein pluralities of the pairs are secured together to form commercially available fuel cells utilized to generate electric power. Material employed between respective pairs of plates are in the nature of resilient media arranged about selected areas of the plates to confine paths for fluids adapted to flow within said selected areas. A method of manufacturing such fuel cell units involves the injection of a rapidly curable liquid silicone material into aligned apertures of the respective plates, whereby liquid silicone material flows through and between the plates to a) seal between respective anode and cathode plates and to b) form an insulation layer on the backside of the anode.
