PROBLEM TO BE SOLVED: To provide a fuel cell system in which leakage of liquid fuel can be easily detected at an early stage thereof even if the amount of its leakage is small and which can be inexpensively manufactured with good workability.SOLUTION: A fuel cell system 1 includes a fuel supply passage 10 through which the liquid fuel is circulated, and a seal member 20 which seals the fuel supply passage 10, and also includes a catalyst 22 which generates gas by being reacted with the liquid fuel leaked out from the seal member 20, and a gas sensor 3 which detects the gas. According to the fuel cell system 1 like this, even if the leakage amount of the liquid fuel is small, its leakage can be easily detected at the early stage of the leakage, and the workability and cost performance can be improved. |
