Abstract: A power generation system has a fuel cell stack and at least one condensation point in the system at which water present after shutdown of the power generation system can condense or collect. Drying after shutdown is improved by maintaining a temperature gradient between the condensation point and at least one other component in the power generation system after shutdown. In one embodiment, the temperature gradient is maintained by housing the fuel cell stack in a thermally insulated container and arranging the condensation point outside of the insulating container. In another embodiment, drying after shutdown is accomplished with an adsorption unit having a water-adsorbing material arranged in a desired location within the power generation system.

Abstract: Improvements in startup time for an electrochemical fuel cell system from freezing and sub-freezing temperatures may be observed by minimizing the coolant volume in the coolant subsystem. In particular, this may be accomplished by having a two pump—dual loop cooling subsystem. During startup, one pump directs coolant through a startup coolant loop and after either the fuel cell stack or the coolant temperature reaches a predetermined threshold value, coolant from a main or standard coolant loop is then directed to the fuel cell stack. In an embodiment, coolant from the standard loop mixes with coolant in the startup loop after the predetermined threshold temperature is reached.

Abstract: An anode supply system for a fuel cell stack having an anode section with a gas inlet and a gas outlet includes a sensor device for determining the fuel content inside the anode supply system. A discharge valve is operable to form a gas-conducting connection between the anode supply system and the environment in an open position, and a control device is configured to actuate the discharge valve. The control device controls the discharge valve based on signals from the sensor device, independently of current performance data of the fuel cell stack.

Abstract: The invention concerns a method to cold-start a fuel cell system at sub-zero temperatures, whereby the fuel cell system comprises a fuel cells stack, upstream of which is connected a heating device to heat a cooling agent to be circulated by a coolant pump. To reduce the demand for stored electrical energy, the method stipulates the following: the cold fuel cell stack is operated at such a capacity that it generates sufficient power to operate the heating device and the coolant pump; the power generated by the fuel cell stack is used to operate the heating device for heating the cooling agent as well as the coolant pump, whereby the coolant pump circulates the cooling agent between the fuel cell stack and the heating device; the heating device is switched off as soon as the fuel cell stack reaches a preset temperature that is higher than the original temperature.
