Abstract

There are provided a hydrogen tank for compressed storage of hydrogen gas, as fuel gas, at high pressures; a fuel cell stack for generating and supplying power using the hydrogen gas from the hydrogen tank; a hydrogen supply path interconnecting the hydrogen tank and the fuel cell stack; a shutoff valve for allowing supply of the hydrogen gas from the hydrogen tank by opening or closing the hydrogen supply path; a fuel supply valve, situated downstream of the shutoff valve, with respect to a supply direction of oxygen gas, for allowing supply of hydrogen gas to fuel cell stack; and an ECU for controllably causing the fuel supply valve to assume its closed state and the shutoff valve to assume its opened state during filling the hydrogen tank with hydrogen gas.

Claims4

Dependent claims

A fuel cell system comprising:

a fuel tank configured to store fuel gas;
a fuel cell stack configured to generate and supply power using the fuel gas from the fuel tank;
a fuel supply path interconnecting the fuel tank and the fuel cell stack;
a shutoff valve configured to allow supply of the fuel gas from the fuel tank by opening or closing the fuel supply path;
a fuel supply valve, situated downstream of the shutoff valve with respect to a supply direction of the fuel gas, configured to allow supply of the fuel gas to the fuel cell stack;
and
a controller configured to control the shutoff valve and the fuel supply valve to control supply of the fuel gas from the fuel tank,
the controller causing the fuel supply valve to assume its closed state and the shutoff valve to assume its opened state during filling the fuel tank with the fuel gas.
