Beschreibung
Zusammenfassung:	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.
