TEMPERATURE CONTROL SYSTEM FOR FUEL CELL

摘要

Provided is a temperature control system which can suppress cell voltage fluctuation even in the case of starting cells under low temperature environment. The temperature control system for the fuel cells controls the temperature of the fuel cells by circulating a heat transfer medium in the fuel cell. The system is characterized in having a circulation control means which circulates the heat transfer medium of a larger flow quantity for low-temperature operation than that for normal operation. Since the flow quantity of the heat transfer medium (cooling water or the like) for low-temperature start is set larger than that for normal start, temperature fluctuation between the cells can be suppressed even in the case of warming for the low-temperature start, and as a result, the cell voltage fluctuation can be suppressed.
