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： A fuel cell system according to one aspect of the invention is operated in an ordinary mode and in a gas leakage detection mode. The fuel cell system includes fuel cells, a fuel gas supplier configured to supply a fuel gas to the fuel cells, a shutoff valve provided in a flow path for leading a flow of the fuel gas supply from the fuel gas supplier to the fuel cells and configured to shut off the fuel gas supply, and a variable pressure regulator provided in the flow path between the shutoff valve and the fuel cells to regulate a pressure of the fuel gas in a downstream in a flow direction of the fuel gas supply to a variable pressure value. In the ordinary mode, the fuel cell system sets the pressure value of the variable pressure regulator to an ordinary power generation pressure value for ordinary power generation. In the gas leakage detection mode, on the other hand, the fuel cell system closes the shutoff valve, sets the pressure value of the variable pressure regulator to a higher value than the ordinary power generation pressure value, and performs leakage detection of the fuel gas from the shutoff valve. Such setting of the pressure value in the variable pressure regulator desirably enables high-speed reduction of the fuel gas pressure in the flow path between the shutoff valve and the variable pressure regulator.

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).
