| 摘要 |
A fuel cell power plant comprises a fuel cell ( 37 ) which generates power by an electrochemical reaction between hydrogen supplied to an anode ( 32 A) and oxygen supplied to a cathode ( 32 B) via an electrolyte membrane ( 32 ). After the fuel cell ( 37 ) has stopped power generation, a cooling device ( 40, 41 ) condenses water vapor which has accumulated around the anode ( 32 A). The condensed water prevents hydrogen remaining at the anode ( 32 A) after the fuel cell ( 37 ) stops generating power, from burning. The cooling device ( 40, 41 ) performs cooling until the fuel cell ( 37 ) falls to a predetermined temperature, and then stops operating.
