摘要： Reactant gas supply streams for solid polymer fuel cells may be heated and humidified using heat generated by the fuel cell and water vapor from the fuel cell exhaust. The heat and water vapor in the oxidant exhaust stream are sufficient to heat and humidify a reactant gas supply stream, preferably the oxidant supply stream. The heating and humidifying can be accomplished by flowing a reactant gas supply stream and a fuel cell exhaust gas stream on opposite sides of a water permeable membrane in a combined heat and humidity exchange apparatus. The method and apparatus are particularly suitable for use with air-cooled fuel cell systems and systems which employ near ambient pressure air as the oxidant gas supply.

摘要： An improved membrane electrode assembly (“MEA”) comprises coextensive ion exchange membrane and electrode layers and a resilient fluid impermeable integral seal comprising a sealant material impregnated into the porous electrode layers in the sealing regions. The integral seal preferably circumscribes the electrochemically active area of the MEA. The integral seal preferably also extends laterally beyond the edge of the MEA. An integral seal may also be provided around any openings, such as external manifold openings formed outside the MEA. Preferably, the uncured sealant material is a flow processable elastomer applied using an injection molding process. In preferred embodiments the seal has a plurality of spaced, parallel raised ribs with cross-ribs extending therebetween at spaced intervals. The raised ribs and cross-ribs provide compartmentalized seals that provide improved protection against fluid leaks.

摘要： An electrochemical fuel cell stack with an improved compression assembly comprises a tension member which is electrically non-conductive and preferably non-metallic. The tension member can be made from a composite material which has similar expansion and contraction properties as the stack materials, thereby reducing undesirable fluctuations in the compressive force applied to the stack. An improved apparatus for securing the improved tension member to the rest of the compression assembly is also provided. Preferred embodiments of an improved compression assembly employ a collet and wedges to grip the tension member and compress a resilient member which imparts a tensile force to the tension member and a compressive force to the fuel cell assemblies. In other embodiments, an improved compression assembly employs a unitary resilient member and fastener in combination with a tension member. The improved apparatus is easier to assemble in high speed manufacturing processes because the compression assembly can be assembled or installed using the same machinery which is used to compress the stack in one fixturing because the compression assembly is assembled by being stacked in essentially the same direction as the other fuel cell components. An improved method of assembling a compression assembly for an electrochemical fuel cell stack is also provided.

摘要： An electrochemical fuel cell assembly with compliant compression mechanism includes a first plate, a second plate, and at least one membrane electrode assembly disposed between the first and second plates. Compliant compression members, such as twisted wire springs or ribbon springs, extend between the first and second plates such that the compression members urge the first plate toward said second plate to compress each membrane electrode assembly interposed between the plates. In operation, compressive force is applied by the compression members to each membrane electrode assembly to maintain electrical conductivity.

摘要： A gas generator includes a reactant capable of producing a gas and a gas outlet valve that can function as both a gas flow valve and a pressure relief vent, using the same gas flow path through the valve. When the valve is closed and the pressure within the gas generator is below a threshold pressure, a moveable valve member is biased against a valve seat to block the outlet port. When gas generator is coupled to the apparatus, an actuator is inserted into the valve, displacing the moveable valve member and separating it from the valve seat to open the valve. When the gas generator is uncoupled, pressure at or above a threshold displaces the moveable member, separating it from the valve seat to open the outlet port so pressure can be released to the external environment.

摘要： A quick connect fitting is provided for connecting a pressure fluid container to an intake port of a consumer system, such as a fuel cell stack. The fitting includes a solenoid-activated valve for controlling outflow of fluid from the pressure fluid container. The valve is biased to a closed position when no electrical power is supplied to the solenoid. In one embodiment the fitting incorporates a coupling mechanism for removable attachment to the intake part of the consumer system.
