Abstract
A fuel cell system for supplying electricity to a main motor as a power source includes a fuel cell stack and pumps for supplying a fuel gas and an oxygen-containing gas to the fuel cell stack. The fuel cell system further includes a driving force transmitting mechanism. The driving force transmitting mechanism connects the main motor, the pumps, and the supercharger for driving the pumps and the supercharger by the main motor.
Claims12
A fuel cell system for supplying electricity to a motor as a power source, said fuel cell system comprising:
- a fuel cell stack formed by stacking electrolyte electrode assemblies and separators alternately, said electrolyte electrode assemblies each including a pair of electrodes and an electrolyte interposed between said electrodes, said fuel cell stack and said motor being connected together;
- a reactant gas supply pump for supplying a reactant gas including at least one of a fuel gas and an oxygen-containing gas to said fuel cell stack;
- and
- a driving force transmitting mechanism for connecting said motor and said reactant gas supply pump to drive said reactant gas supply pump by said motor.
