A hydrogen gas supply device supplies hydrogen gas to a fuel cell stack and includes an electromagnetic pressure regulating valve that regulates the pressure of the hydrogen gas to low pressure. The electromagnetic pressure regulating valve includes a housing, and a valve passage connecting a primary port and a secondary port is formed in the housing. A valve body controls an opening degree of the valve passage and is provided in the housing. A high-pressure sealing member and low-pressure sealing member are provided on an outer periphery of the valve body. The high-pressure sealing member and the low-pressure sealing member are provided in this order from one end side of the valve body to the other end side thereof. The electromagnetic pressure regulating valve further includes a housing pressure equalizing passage connecting the secondary port and a buffer chamber formed between the high-pressure sealing member and the low-pressure sealing member.

A system for adjusting temperature of cooling-liquid comprises: a radiator; a cooling-liquid circulation flow-channel; a radiator bypass flow-channel; a thermostat valve; and a valve bypass flow-channel through which the cooling-liquid of the radiator bypass flow-channel is allowed to flow in a predetermined amount even if the thermostat valve is completely closed.

A fuel gas supply device for supplying fuel gas to a fuel cell stack includes a control valve provided in a fuel gas path connecting a fuel tank and the fuel cell stack, an upstream-side pressure sensor and a downstream-side pressure sensor for detecting an upstream-side pressure and a downstream-side pressure, and a programmable controller. The programmable controller calculates a required opening based on a target fuel gas pressure and the downstream-side pressure and calculates an opening time and a closing time based on the required opening and the upstream-side pressure, or calculates an opening time and a closing time based on the target fuel gas pressure and the downstream-side pressure and calculates a required opening based on the opening time and the upstream-side pressure, and controls the control valve using the calculated required opening, opening time and closing time.
