摘要： In a fuel cell assembly, a passive gas spring is disposed between the stack and the supporting structure for maintaining compressive force on the stack and manifold seal. As variation in temperature of the assembly and structure causes dimensional changes therein, the pressure within the gas spring also changes accordingly. The gas spring is provided with inlet and outlet check valves, the outlet check valve opening to expel air when internal spring pressure reaches a predetermined upper pressure limit, and the inlet check valve opening to admit air when the internal spring pressure falls below a predetermined lower pressure limit in a currently preferred embodiment, the outlet check valve allows exit of gas from the gas spring at pressures exceeding 5 psig, to prevent rupture of the gas spring, and the inlet check valve allows entrance of gas into the gas spring as the spring cools following use.

摘要： An electrochemical power generation system includes a fuel cell stack having an oxidant delivery system, an oxygen sensor for measuring the oxygen concentration of ambient air in the vicinity of the power generation system, and a hydrogen concentration sensor for measuring a hydrogen concentration in the ambient air in the vicinity of the power generation system. A controller is configured to cease operation of the power generation system, for example ceasing delivery of fuel to the fuel cell stack, when either the hydrogen concentration measured by the hydrogen concentration sensor exceeding a hydrogen concentration threshold or the oxygen concentration measured by the oxygen sensor falling below an oxygen concentration threshold.

摘要： A device used for air supply of a fuel cell has an expander and a compressor that is at least partially driven thereby. The hot gases of combustion at least occasionally flow through the expander. After flowing through the expander, the exhaust gases emit at least a portion of the residual thermal energy remaining in them to at least one of the fuel flows supplied for combustion and during a cold start especially also to the cooling circuit of the fuel cell. A device of this type may be used, for example, in a mobile fuel cell system.

摘要： Auxiliary fuel cell system that provides backup power to a primary power source, and energy-consuming systems that are otherwise associated with at least one primary power source and at least one auxiliary fuel cell system. The auxiliary fuel cell system includes at least one fuel cell stack that is adapted to produce an electric current from a fuel and an oxidant, such as from hydrogen and oxygen gases. The auxiliary fuel cell system further includes a source of fuel, such as a source of hydrogen gas, and this source may include a fuel processor that is adapted to produce the hydrogen gas or other fuel. The energy-consuming system is adapted to selectively draw an electric current from a primary power source or an auxiliary fuel cell system. A Source selection system selectively establishes electrical communications between an energy-consuming system and the primary power source or the auxiliary fuel cell system.
