    摘要: A fuel cell system includes a controller, a fuel cell stack, a fuel inlet conduit operatively connected to the fuel cell stack, the fuel inlet conduit adapted to receive fuel from a fuel supply, a recycling conduit operatively connecting the fuel cell stack to the fuel inlet conduit, the recycling conduit adapted to recycle a portion of a fuel exhaust stream from the fuel cell stack to the fuel inlet conduit, and an ammonia or hydrazine storage vessel operatively connected to the fuel inlet conduit via a valve coupled to the controller. The controller is configured to control the operation of the valve to provide ammonia or hydrazine from the ammonia or hydrazine storage vessel into the fuel inlet conduit upon detecting a change in the fuel from the fuel supply.

    摘要: A method for operating a fuel cell system during an interruption includes identifying a load interruption in which an external load is partially or fully unable to draw electrical power from the fuel cell system. At least a first fuel cell column of the fuel cell system is operated in an electrolysis mode such that the first fuel cell column generates fuel during the load interruption. Power is provided to the first fuel cell column in the electrolysis mode from at least a second fuel cell column of the fuel cell system. The second fuel cell column is operating in a normal power generation operating mode.
