PROBLEM TO BE SOLVED: To provide a fuel cell system capable of inexpensively and accurately determining, by using a temperature sensor, the presence/absence of reformed water supply before the fuel cell system starting start-up operation.SOLUTION: A fuel cell system includes: a temperature sensor (27) that is disposed between a reformed water pump (11b1) of a reformed water supply pipe (11b) and an evaporation part (32); and a controller (15) for determining that reformed water has been supplied at a predetermined water level of the reformed water supply pipe (11b) on which the temperature sensor (27) is disposed, before the fuel cell system starts start-up operation, on the basis of change in the temperature sensor (27)'s detection temperature caused by reformed water supplied to the reformed water supply pipe (11b) by drive of the reformed water pump (11b1).SELECTED DRAWING: Figure 1 |
