A fuel cell power plant comprises a fuel cell stack (1) constituted by aplurality of fuel cells which perform electric power generation by means of areaction of hydrogen and oxygen. A controller (16) determines whether or notmoisture inside the fuel cell stack (1) is frozen, and if the moisture is frozen,the controller (16) causes the fuel cell stack (1) to perform intermittent electricpower generation via an inverter (27) while continuing to supply oxygen to thefuel cell stack (1). The fuel cell stack (1) generates heat as a result of theelectric power generation, whereby moisture is generated in a cathode (9).During the periods in which electric power generation is not performed, theoxygen which is supplied to the cathode (9) of the fuel cells scavenges thegenerated moisture, thereby ensuring the supply of oxygen to the cathode (9)during electric power generation. |
