Abstract
A fuel cell system includes a fuel cell stack configured to generate electricity, an anode exhaust and a cathode exhaust, an anode tail gas oxidizer (ATO) configured to oxidize the anode exhaust using the cathode exhaust, and a low-temperature oxidizer (LTO) configured to catalyze oxidation of carbon monoxide (CO) in the cathode exhaust output from the ATO.
