Abstract
A fuel cell system includes a controller for controlling a linear solenoid valve and an injector, and a temperature sensor for measuring the outside temperature or the temperature of refrigerant that cools an FC stack. When supplying hydrogen gas to the FC stack while a measurement value of the temperature sensor is equal to or less than a predetermined temperature, the controller causes a linear solenoid valve to inject hydrogen gas while maintaining the opening degree of the linear solenoid valve at a predetermined temperature and simultaneously causes the injector to intermittently inject hydrogen gas.
Claims2
A fuel cell system comprising:
- a fuel cell;
- a fuel supply passage for supplying fuel to the fuel cell;
- an ejector provided in the fuel supply passage;
- a first fuel injection device configured to inject the fuel into the ejector while maintaining an arbitrary opening degree between a fully-closed opening degree and a fully-open opening degree;
- a second fuel injection device configured to intermittently inject the fuel into the ejector;
- a fuel circulation passage for circulating unused fuel discharged from the fuel cell back to the ejector, which is a part of the fuel supplied to the fuel cell;
- a controller for controlling the first fuel injection device and the second fuel injection device;
- and
- a temperature measurement part for measuring an outside temperature or a temperature of refrigerant that cools the fuel cell,
- wherein when supplying the fuel to the fuel cell while a measurement value of the temperature measurement part is equal to or less than a predetermined temperature, the controller causes the first fuel injection device to inject the fuel while maintaining an opening degree of the first fuel injection device at a predetermined opening degree, and simultaneously causes the second fuel injection device to intermittently inject the fuel.
