摘要： An object of the present invention is to provide a hydrogen gas supply device including a pressure regulating valve capable of controlling the flow rate (or pressure) of hydrogen to the fuel cell stack with a high degree of accuracy even if upstream pressure is high and preventing hydrogen gas leakage to the atmosphere.
A hydrogen gas supply device 1 configured to supply a hydrogen gas to a fuel cell stack 3 includes an electromagnetic pressure regulating valve 14 configured to regulate the pressure of the hydrogen gas to low pressure. The electromagnetic pressure regulating valve 14 includes a housing 21, and a valve passage 22 connecting a primary port 21a and a secondary port 21c is formed in the housing 21. A valve body 24 configured to control an opening degree of the valve passage is provided in the housing 21. A high-pressure sealing member 28 and a low-pressure sealing member 29 are provided on an outer periphery of the valve body 24. The high-pressure sealing member 28 and the low-pressure sealing member 29 are provided in this order from one end side of the valve body 24 to the other end side thereof. The electromagnetic pressure regulating valve 14 further includes a housing pressure equalizing passage 34 connecting the secondary port 21c and a buffer chamber 30 formed between the high-pressure sealing member 28 and the low-pressure sealing member 29.

摘要： 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.
