PROBLEM TO BE SOLVED: To reduce a carbon monoxide concentration in a reformed gas supplied to a fuel cell from a reformer as much as possible to prevent poisoning of a catalyst, and improve power generating efficiency. SOLUTION: This fuel cell system generating an electromotive force by an electrochemical reaction of a reformed gas supplied from a reformer has reformed gas supply permission means (steps S2, S3, S4, S6) permitting supply of a reformed gas from the reformer to a fuel cell in the case that two among temperature at prescribed positions of the reformer, a carbon monoxide concentration in the reformed gas, and an amount related to a voltage of the fuel cell satisfy prescribed conditions. |
