摘要： A heat regulating system for an electrochemical conversion assembly. In one embodiment, the electrochemical conversion assembly is a fuel cell, and the device includes one or more fluid-manipulating components to vary the amount of a coolant or related heat regulating fluid used to maintain a preferred temperature in the fuel cell. Preferred fuel cell operating temperatures can be more easily achieved by selectively bypassing a portion of the coolant around the fuel cell during certain temperature or power demand regimes. A controller can be used to monitor and selectively vary the extent to which at least one of these components modifies the flow of fluid past the fuel cell.

摘要： Systems of checking thermal-induced circulation of a coolant in a fuel cell stack are disclosed. The system includes coolant inlet and outlet lines extending from a fuel cell stack. A pump and a radiator are confluently connected to the coolant inlet and coolant outlet lines. In one embodiment, a valve (either check type or automatic type) is provided in the coolant outlet line at the bottom of the fuel cell stack to prevent the flow of cold coolant from the coolant outlet line into the fuel cell stack upon start-up of the fuel cell stack. In another embodiment, a valve (either one-way flow control type or automatic type) is provided in the coolant inlet line at the top of the fuel cell stack. A method of checking thermal-induced circulation of a coolant in a fuel cell stack is also disclosed.

摘要： A fuel cell system including a combined injector/ejector system. The pressure of a hydrogen gas being injected into the fuel cell system by the injector acts as a pump that draws an anode exhaust gas being carried by the ejector back into the fuel cell system. The respective gases mix together in proximity to the ejector prior to being introduced back into the fuel cell system. A pressure controller can be provided to control the pressure of the hydrogen gas applied to the injector to more effectively draw the anode exhaust gas. In this manner, the need for a separate pump for the ejector, and the energy required for its operation, is eliminated or at least lessened, thus increasing the overall energy efficiency of the fuel cell system.
