PURPOSE:To keep fuel/oxidizer utilization factor of a fuel cell main body, and a battery voltage within a proper range even in the case where characteristic unbalance is generated between the fuel cell main bodies. CONSTITUTION:Fuel cell main bodies 1 each comprising a fuel pole and an oxidizer pole are electrically connected to each other in the number of (n) (n>=1) serially to form a string 2, and such strings 2 are electrically connected in parallel in the number of (m) (m>=2). To each string 2, a string current detector 31 is connected separately. A fuel supply damper 32 and an oxidizer supply damper 33 are provided on each fuel supply header 19 and an oxidizer supply header 20 of each string 2 respectively. Each fuel supply damper 32 and each oxidizer supply damper 33 adjust ratio of fuel flow and oxidizer flow to be supplied to each string 2 based on each string current detection value obtained by each string current detector 31. |
