Claim 9:
10. The method according to claim 9, wherein
the calculating of the second humidity in the air exhausted from the fuel cell through the air supply path includes:
calculating a flow rate WVout of water vapor in the air exhausted from the fuel cell on a basis of an expression: WF2−(WF1−Ow), in which WF2 denotes the second mass flow rate of the air exhausted from the fuel cell, WF1 denotes the first mass flow rate of the air supplied to the cathode electrode, and Ow denotes the mass flow rate of the oxygen consumption, wherein
the calculating of the second humidity in the air exhausted from the fuel cell is on a basis of a ratio of the calculated flow rate WVout of the water vapor to an amount of saturated water vapor in the air exhausted from the fuel cell corresponding to a temperature value of the air exhausted from the fuel cell.
