摘要： A method of operating the fuel cell stack having an anode side and a cathode side by flowing hydrogen into the anode side and flowing air into the cathode side. The fuel cell produces electricity that is used to operate a primary electrical device. To shut down the stack in one embodiment, the primary electrical device is disconnected from the stack. The flow of air into the cathode side is stopped and positive hydrogen pressure is maintained on the anode side. The fuel cell stack is shorted and oxygen in the cathode side is allowed to be consumed by hydrogen. The inlet and outlet valves of the anode and the cathode sides are closed. Thereafter, the flow of hydrogen into the anode side is stopped and the flow of exhaust from the cathode side is stopped.

摘要： A fuel cell stack module that includes a fuel cell stack and an end unit that are part of a thermally integrated assembly. The module also includes a charge air cooler and a WVT unit integrated within the end unit. A cooling fluid is pumped through a line in the end unit and the fuel cell stack by a pump. The cooling fluid is pumped through the charge air cooler to reduce the temperature of the cathode inlet airflow sent to the fuel cell stack. The reduced temperature cathode inlet air from the charge air cooler is sent to the WVT unit where it is humidified. Cathode exhaust gas from the fuel cell stack can be sent to the WVT unit to provide the humidification to humidify the cathode inlet air. A by-pass valve provided within the end unit can be employed to by-pass the WVT unit during cold-starts.

摘要： A technique for determining whether a cooling fluid pump used for pumping a cooling fluid through a fuel cell stack has failed. The technique includes measuring the temperature of the cooling fluid at the output from the stack and/or measuring the cathode exhaust gas temperature as close as possible to the cathode outlet of the stack. The measured temperature is compared to a temperature that would be expected under the current operating conditions of the fuel cell system in a controller. If the difference between the measuring temperature and the expected temperature is large enough, then the controller provides a warning signal of pump failure, and also possibly reduces the stack outlet power.

摘要： A fuel cell system that employs a split fuel cell stack, where fresh anode gas is humidified by water trap humidifiers. The fuel cell system includes a plurality of valves that are opened and closed to provide stack order switching between the split stacks so that the flow of hydrogen through the stacks is always in the same direction. A water trap humidifier is provided at the anode inlet to both split stacks, possibly in the anode inlet manifold or fuel cell non-active region, to provide the humidification. The valves are selectively opened and closed to provide fresh hydrogen to one stack, and humidified hydrogen to the other stack.
