    摘要： A fuel cell system includes a first fuel cell stack, a second fuel cell stack arranged in a cascade configuration with the first fuel cell stack, and at least one hydrocarbon fuel reformer which is thermally integrated with at least a portion of the first stack. The system is configured such that in operation, at least partial reformation of hydrocarbon fuel occurs prior to entry into the first stack or in the first stack, and the second stack uses fuel exhaust from the first stack as fuel. A method of operating the fuel cell system includes reforming a hydrocarbon fuel to form a reformed fuel while cooling at least a portion of a first fuel cell stack, generating electricity in the first fuel cell stack using the reformed fuel, providing a fuel exhaust stream from the first fuel cell stack into a second fuel cell stack, and generating electricity in the second fuel cell stack using the fuel exhaust stream from the first fuel stack as a fuel.

    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.
