PURPOSE:To improve follow-up properties responding to a rotation speed and control of an accelerator, by a method wherein a control valve, the opening area of which is changed according to a rotation speed, and a control valve, the opening area of which is varied in linkage with control of an accelerator. CONSTITUTION:A machine valve 14, responding to control of an accelerator, a flow rate proportional solenoid 13, the opening of which is varied in response to the rotation speed of an engine, and a pressure regulator 12 are located up a line from a gas fuel feed valve 3, the feed of hydrogen gas from a hydrogen occlusion alloy tank 10 is controlled. This constitution enables variation of a gas fuel feed amount according to the rotation speed of an engine even if control of an accelerator is fixed, and enables variation of an output torque through control of the accelerator even if a rotation speed is constant.
