Abstract
A fuel cell system that includes a control system for regulating the power produced by the fuel cell system. The fuel cell system includes a fuel cell stack adapted to produce electrical power from a feed. In some embodiments, the fuel cell system includes a fuel processing assembly adapted to produce the feed for the fuel cell stack from one or more feedstocks. The control system regulates the power produced by the fuel cell system to prevent damage to, and/or failure of, the system.
Claims26
A method for operating a fuel cell system that is adapted to receive an applied load and which comprises a fuel processing assembly adapted to produce a feed stream containing hydrogen gas, and a fuel cell system having a currently available power output and adapted to receive at least a portion of the feed stream and to produce electrical power therefrom, the method comprising:
- producing a feed stream with the fuel processing assembly operating at a rate of production of the feed stream;
- delivering at least a portion of the feed stream to a fuel cell stack;
- and
- selectively diverting a portion of the feed stream from delivery to the fuel cell stack if the applied load is less than the currently available power output.
