摘要： In a fuel cell system of the invention, a hydrogen leakage detection process closes a shutoff valve, which shuts off a supply of hydrogen from a hydrogen supply unit into a hydrogen supply flow path, and opens a pressure regulator, which reduces a pressure of hydrogen in the hydrogen supply flow path, so as to keep the hydrogen supply flow path in a state with no pressure regulation and make the fuel cell system in a leakage detectable state. In this leakage detectable state, the hydrogen leakage detection process measures at least one of a pressure and a flow rate as a state quantity of hydrogen in the hydrogen supply flow path that feeds the supply of hydrogen to fuel cells. The hydrogen leakage detection process analyzes a detected behavior of the state quantity in the leakage detectable process and specifies the occurrence of a hydrogen leakage in the downstream of the hydrogen supply unit. This arrangement enables highly accurate detection of a hydrogen leakage in the fuel cell system with the pressure regulator provided in the hydrogen supply flow path.

摘要： In a fuel cell system (100), the amount of fuel gas supplied through an fuel gas supply passage (24) and the amount of fuel gas consumed by a fuel cell (10) are detected. A difference between the amount of supplied fuel gas and the amount of consumed fuel gas is calculated by subtracting the amount of consumed fuel gas from the amount of supplied fuel gas. The pressure of the fuel gas in a leak detection passage (Cx), the change in the pressure of the detected fuel gas can be detected, and the change in the amount of fuel gas in the gas leak detection passage (Cx) due to the change in the pressure of the fuel gas can thus be detected. The difference is corrected by subtracting the change in the amount of fuel gas in the gas leak detection passage from the difference. When the corrected difference is equal to or greater than a predetermined value, a fuel gas leak is detected in the leak detection passage (Cx).
