Abstract
A fuel cell system having a hydrogen supply path for supplying a hydrogen gas to a fuel cell, an injector which is provided in the hydrogen supply path and which regulates the pressure of the gas on the upstream side of the hydrogen supply path to inject the pressure-regulated hydrogen gas to the downstream side of the hydrogen supply path, and a surge tank 81 which is provided in the hydrogen supply path on the upstream side from the injector and which suppresses the fluctuation of the pressure of the gas in the hydrogen supply path.
Claims12
A fuel cell system comprising:
- a fuel cell;
- a fuel gas supply path which allows a fuel gas supplied from a fuel supply source to flow into the fuel cell;
- a variable gas supply device which regulates the state of the gas on the upstream side of the fuel gas supply path to supply the gas to the downstream side and which injects and supplies the fuel gas;
- and
- a surge tank which is provided in the fuel gas supply path on the upstream side from the variable gas supply device and which suppresses the fluctuation of the pressure of the gas in the fuel gas supply path.
A fuel cell system comprising:
- a fuel cell;
- a fuel gas supply path which allows a fuel gas supplied from a fuel supply source to flow into the fuel cell;
- a variable gas supply device which regulates the state of the gas on the upstream side of the fuel gas supply path to supply the gas to the downstream side and which injects and supplies the fuel gas;
- and
- an expanded transverse sectional portion disposed in the fuel gas supply path on the upstream side from the variable gas supply device,
- wherein the expanded transverse sectional portion has at least a larger transverse section than on the upstream side thereof.
A fuel cell hybrid vehicle comprising:
- a fuel cell;
- a fuel gas supply path which allows a fuel gas supplied from a fuel supply source to flow into the fuel cell;
- a variable gas supply device which regulates the state of the gas on the upstream side of the fuel gas supply path to supply the gas to the downstream side and which injects and supplies the fuel gas;
- and
- a surge tank which is provided in the fuel gas supply path on the upstream side from the variable gas supply device and which suppresses the fluctuation of the pressure of the gas in the fuel gas supply path,
- wherein the surge tank is disposed between the variable gas supply device and a passenger space.
