Abstract
A fuel cell system includes a fuel cell stack for receiving a supplied reactant gas to generate a power; an air compressor for removing moisture remaining in the fuel cell stack during the stop of the power generation; a secondary cell for supplying an operative power to the air compressor; and a controller for controlling the balance of water flowing into and out of the fuel cell stack so that a time required to remove the moisture remaining in the fuel cell stack by the air compressor is substantially constant.
Claims4
A fuel cell system comprising:
- a fuel cell stack configured to receive a supplied reactant gas to generate power;
- a removal device configured to remove moisture from the fuel cell stack during the stop of the power generation;
- an accumulator device configured to supply an operative power to the removal device;
- and
- a water balance control device programmed to control the balance of water flowing into and out of the fuel cell stack so that a time required to remove the moisture from the fuel cell stack by the removal device is substantially constant.
