PROBLEM TO BE SOLVED: To restrain coking of reforming catalyst in a reforming unit of a fuel cell system without incurring increased complexity and cost of the system.SOLUTION: In a fuel cell system, on the basis of a first map indicating relationship between a reforming unit inlet temperature and a first correction S/C and a reforming unit inlet temperature detected by a reforming unit inlet temperature sensor, a first correction S/C corresponding to the detected reforming unit inlet temperature is calculated (step 204). Similarly, on the basis of a second map indicating relationship between a fuel cell temperature and a second correction S/C and a fuel cell temperature detected by a fuel cell temperature sensor, a second correction S/C corresponding to the detected fuel cell temperature is calculated (step 208). A reference S/C which is a reference S/C, the first correction S/C calculated by first correction S/C calculation means, and the second correction S/C calculated by second correction S/C calculation means are added together to calculate a target S/C (step 210). Thus, a reform water supply flow rate is controlled on the basis of the calculated target S/C (step 212). |
