20110311891 | Fuel Cell Based Power Generation Systems and Methods of Operating the Same - 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. | 12-22-2011 |
20090220830 | ANODE SUPPLY SYSTEM FOR A FUEL CELL STACK AND A METHOD OF PURGING THE SAME - 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. | 09-03-2009 |
