Abstract: A fuel cell assembly has a plurality of fuel cell component elements extending between a pair of end plates to form a stack, and plural reactant gas manifolds mounted externally of and surrounding the stack, in mutual, close sealing relationship to prevent leakage of reactant gas in the manifolds to the environment external to the manifolds. The reactant gas manifolds are configured and positioned to maximize sealing contact with smooth surfaces of the stack and the manifolds. One embodiment is configured for an oxidant reactant manifold to overlie the region where the fuel reactant manifold engages the stack. Another embodiment further subdivides an oxidant reactant manifold to include a liquid flow channel, which liquid flow channel overlies the region where the fuel reactant manifold engages the stack.

Abstract: The multi-section cathode air heat exchanger (102) includes at least a first heat exchanger section (104), and a fixed contact oxidation catalyzed section (126) secured adjacent each other in a stack association. Cool cathode inlet air flows through cool air channels (110) of the at least first (104) and oxidation catalyzed sections (126). Hot anode exhaust flows through hot air channels (124) of the oxidation catalyzed section (126) and is combusted therein. The combusted anode exhaust then flows through hot air channels (112) of the first section (104) of the cathode air heat exchanger (102). The cool and hot air channels (110, 112) are secured in direct heat exchange relationship with each other so that temperatures of the heat exchanger (102) do not exceed 800° C. to minimize requirements for using expensive, high-temperature alloys.

Abstract: A fuel cell installation includes a support structure and a cell stack assembly that is removably insertable into the support structure from an uninstalled position to an installed position during an installation procedure. The cell stack assembly includes a fitting. An interfacing structure is mounted on one of the support structure in the cell stack assembly. The interfacing structure carries a connector that is configured to receive the fitting in interconnected relationship. At least one of the fitting and the connector floats in a plane relative to the support structure during the installation procedure. In operation, the fitting engages the connector when the cell stack assembly is inserted into the support structure. The fitting is repositioned relative to the connector to ensure that the fitting and connector are aligned with one another and connected upon installation.

Abstract: A membrane electrode assembly may be made using a one-sided catalyst coated membrane (CCM) wherein only one catalyst layer, either the anode or the cathode, is coated directly on the ion-exchange membrane. In particular, a one-sided CCM may be used where it may not be practicable to coat both sides of the ion-exchange membrane with catalyst layers such as when PTFE is added to the anode catalyst layer to render it reversal tolerant.

Abstract: A fuel cell system for powering a work load includes a fuel cell stack and a shunt regulator having a threshold detection; transistorized power switching element, and a dump load. The threshold detection element identifies when an abnormally high voltage rises. The power switching element routes power from the high voltage buss to the dump load. The dump load acts as an electrical energy sink, and may provide dissipated energy to the fuel cell stack in the form of heat. The switching element can also shunt power to the dump load when a digital control signal is set, for example at startup or during cold start conditions.
