Fuel cell plates with injection-molded seals

Fuel cell plates with injection-molded seals

A fuel cell unit (10) incorporates a pair of anode and cathode plates (12,14). Seals employed between respective pairs of plates (12,14) are in the nature of resilient beads (18,20) arranged about selected areas of the plates to confine paths for fluids adapted to flow within said selected areas.

description A fuel cell unit (10) incorporates a pair of anode and cathode plates (12,14). Seals employed between respective pairs of plates (12,14) are in the nature of resilient beads (18,20) arranged about selected areas of the plates to confine paths for fluids adapted to flow within said selected areas. A combination sealing and bonding method for manufacturing such fuel cell units involves the injection of a rapidly curable liquid silicone into aligned mold gating apertures (48,50) of the respective pairs of the plates, whereby liquid silicone flows through and between the plates to a) seal between respective anode and cathode plates pairs and to b) form an insulation layer (16) on the backside of the anode (12).
