<P>PROBLEM TO BE SOLVED: To improve operation efficiency of a fuel cell while securing a request output to the fuel cell. <P>SOLUTION: A control device 24 of a fuel cell system 10 sets a request output of a fuel cell stack 11 required according to a current power request, and predicts a current according to the request output and a temperature of the fuel cell stack 11 from a preset and predetermined output status map. The control device 24 sets an operation status amount according to the predicted current and the temperature of the fuel cell stack 11 from a preset and predetermined operation status amount map. The control device 24 sets the operation status amount to at least any one of a pressure at an air supply port 11a of air supplied to a cathode electrode of the fuel cell stack 11, air utilization ratio at the cathode electrode, a flow rate of a cooling medium cooling the fuel cell stack 11, and a humidity of the air at the air supply port 11a. <P>COPYRIGHT: (C)2013,JPO&INPIT |
