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.
