Abstract
A fuel cell generates electric power by circulating diluted fuel in a fuel cell. In a circulation dilution fuel cell system, a path is provided for leading vapor generated at an air pole of a fuel cell to a dilution fuel tank which circulates the diluted fuel of a fuel cell. Or, a fuel supply tank is provided in the upper position of the dilution fuel tank, so that the liquid fuel can be supplied to the dilution fuel tank by means of gravity. Thus, a pump for supplying the liquid fuel can be eliminated, and power consumption for controlling the fuel cell can be reduced.
Claims18
A liquid circulation type fuel cell comprising:
- a fuel cell for generating electric power using liquid fuel;
- a dilution fuel tank for retaining diluted fuel in which the liquid fuel is mixed with water;
- a circulation path of the diluted fuel for circulating the diluted fuel to the fuel cell, at least having a circulation pump;
- a water supply path for leading vapor generated at an air pole of the fuel cell to the dilution fuel tank, and supplying water to the dilution fuel tank;
- and
- a fuel supply tank for supplying the liquid fuel to the dilution fuel tank.
