Abstract (en)

[origin: WO2007014129A1] A four-step partial pressure swing adsorption method and apparatus is provided for gas separation, such as for recovering fuel from the fuel exhaust of a fuel cell stack. 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 partial pressure swing adsorption, and providing the hydrogen separated from the fuel exhaust stream into the fuel inlet stream.
