FUEL CELL |
摘要 |
A fuel cell stack includes a plurality of cells each including an MEA 10 sandwiched by separators 20. A hydrogen gas supply pipe 31 and an air supply pipe 32 for externally supplying gas, and a hydrogen gas discharge pipe 35 and an air discharge pipe 36 for discharging unreacted gas are connected to the stack. Gas-supply-side valves 33 and 34 are installed in the pipes 31 and 32, respectively. Gas-discharge-side valves 37 and 38 are installed in the pipes 35 and 36, respectively. The valves 33 and 37 close an anode-electrode-layer-side space including an anode electrode layer. The valves 34 and 38 close a cathode-electrode-layer-side space including a cathode electrode layer. This structure prevents introduction of new air, thereby suppressing an increase in the concentration of nitrogen gas in the anode-electrode-layer-side space. |
