Abstract

See full text

A fuel cell system includes a fuel cell. The fuel cell includes an anode having an anode inlet configured to receive anode feed gas, and an anode outlet configured to output anode exhaust. The fuel cell further includes a cathode having a cathode inlet and a cathode outlet. The fuel cell system further includes an anode blower configured to receive the anode exhaust and output a higher-pressure anode exhaust. The fuel cell system further includes an anode blower recycle line configured to receive a portion of the higher-pressure anode exhaust downstream from the anode blower and to output the portion of the higher-pressure anode exhaust upstream from the anode blower. The fuel cell system further includes a first valve disposed in the blower recycle line, the first valve configured to open when the anode of the fuel cell is under-pressurized.
