Abstract
A method of operating a fuel cell system includes providing a fuel inlet stream into a fuel cell stack, operating the fuel cell stack to generate electricity and a hydrogen containing fuel exhaust stream, separating at least a portion of hydrogen contained in the fuel exhaust stream using a high temperature, low hydration ion exchange membrane cell stack, and providing the hydrogen separated from the fuel exhaust stream into the fuel inlet stream.
