Seal retention mechanism for a fuel cell assembly having two plates is disclosed. The seal retention mechanism includes first and second fuel cell plates. The first fuel cell plate has a seal groove that includes at least one aperture formed through a base of the groove. The second fuel cell plate is positioned adjacent to the first fuel cell. The second fuel cell has a cavity in general alignment with the aperture of the first fuel cell plate. The seal groove, aperture and cavity are filled with seal material whereby a portion of the seal material forms a bridge between the first and second fuel cell plates. The seal material at least partially fills the cavity such that the seal groove, aperture, and cavity cooperate to retain the seal material within the seal groove after curing.

A humidifier for a fuel cell system comprises a stack of thin plates having planar sealing surfaces at their edges. A water permeable membrane is provided between each pair of plates. Each plate defines a gas flow passage along its top and bottom surfaces, with an inlet and outlet defined along edges of the plate, and a flow field extending between the inlet and outlet openings. Inlet and outlet passages connect the inlet and outlet openings to the flow field, and the planar sealing surfaces on both sides of the plate include bridging portions which extend across the inlet and outlet passages. Support structures are provided throughout the flow field and the inlet and outlet passages to support the membrane and diffusion medium layer(s). The support structures may optionally be connected together by webs having holes for flow distribution between the top and bottom of each plate.

A method of welding two workpieces together is described. A conductor in electrical communication with a pulse circuit is provided. A portion of the second workpiece is located adjacent the conductor. The two workpieces are also located together. A portion, or all, of one workpiece is welded to the other by applying a pulse current to one of the workpieces. A method of forming a workpiece is disclosed using a pulse current to move the workpiece into a desired shape.

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. Seals employed between respective pairs of plates are in the nature of resilient beads 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 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 on the backside of the anode.
