In an air-cooled fuel cell system ( 10 ), a controlling apparatus ( 100 ) performs a temperature controlling process on the basis of the temperature of a fuel cell detected by a temperature sensor ( 500 ). At this time, if the cell temperature is greater than a target temperature Ta and if the cell temperature is less than a threshold temperature Tth for defining a boundary between (i) a temperature group TG 1 , in which a change in a cell voltage is small relative to the stoichiometric ratio of the air for power generation, and (ii) a temperature group TG 2 , in which a change in the cell voltage is large relative to the stoichiometric ratio of the air for power generation, the controlling apparatus ( 100 ) controls an air supplying apparatus ( 210 ) to increase the amount of the air supplied to an air intake manifold ( 320 ). If the cell temperature is equal to or greater than the threshold temperature Tth, the controlling apparatus ( 100 ) controls a variable valve ( 400 ) to increase the amount of the air flowing into a cooling air channel portion ( 315 ) without an increase in the amount of the air flowing into a power generating air channel portion 314. |
