Abstract
A polymer electrolyte fuel cell system with a polymer electrolyte fuel cell is made up of a cell main body, a mixture generator for generating a gas-liquid mixture by mixing fuel gas which has been supplied from a fuel gas supply with water, and a means for supplying the gas-liquid mixture to the anode-side channels. The gas-liquid mixture allows the solid-polymer film to be moistened without humidifying fuel gas and oxidant gas with a humidifier, and the cell main body to be cooled down without providing a cooling channel therein.
Claims12
A solid-polymer fuel cell system, comprising:
- a cell main body comprising:
- a plurality of unit cells, each of the plurality of unit cells comprising an anode layer, a cathode layer and a solid-polymer film disposed between the anode layer and the cathode layer;
- and
- a plurality of plates, each provided with a plurality of channels facing a respective anode layer, the plurality of unit cells and the plurality of plates being accumulated alternately, the cell main body being provided with a manifold in communication with each channel of the plurality of plates;
- a gas-liquid mixture generator, which is located in the manifold and is supplied with liquid water and fuel gas separately, for internally generating a gas-liquid mixture and for supplying the plurality of channels with the generated gas-liquid mixture;
- and
- an oxidizing gas supply in communication with the cathode layers for supplying the cathode layers with oxidizing gas.
