FUEL CELL SYSTEM WITH LOW-EFFICIENCY POWER GENERATION CONTROL IN DRY STATE

摘要

To quickly and optimally control the water conditionand temperature of a fuel cell even when the fuel cell isat a low temperature and in a dry state. If it isdetermined that a fuel cell is in a dry state (YES in stepS120) and is determined that the fuel cell is at a lowtemperature (YES in step S130), a control device performslow-efficiency power generation (step S140). Performingthe low-efficiency power generation makes it possible toquickly warm up the fuel cell and bring the cathode waterbalance of a fuel cell 2 into a plus (wet) state, so thatthe water condition and temperature of the fuel cell can bequickly and optimally controlled.
