Abstract
The regenerative fuel cell system includes a fuel cell, a water tank that stores water discharged from the fuel cell, a recombiner that is disposed in the water tank and generates water by combining hydrogen and oxygen, and a water electrolyzer that generates hydrogen and oxygen by electrolyzing the water supplied from the water tank. The internal pressure of the water tank storing the water is lower than the internal pressure of the fuel cell during power generation and the internal pressure of the water electrolyzer during electrolysis.
Claims4
A regenerative fuel cell system, comprising:
- a fuel cell;
- a water tank that stores water that is discharged from the fuel cell;
- a recombiner that is disposed in the water tank, and that combines hydrogen and oxygen to produce water;
- and
- a water electrolyzer that produces hydrogen and oxygen by electrolyzing water that is supplied from the water tank, wherein
- internal pressure of the water tank that stores water is lower than internal pressure of the fuel cell during power generation and internal pressure of the water electrolyzer during electrolysis.
