Abstract:
1. A fuel cell system comprising: (A) a fuel cell stack comprising at least one unit fuel cell comprising a cathode, a anode, and a polymer electrolyte membrane interposed therebetween; (B) a detecting device for detecting lack of humidification in said fuel cell stack; (C) a water supplying device for supplying moisture to said fuel cell stack when lack of humidification is detected by said detecting device; (D) a heating device for heating said supplied moisture; (E) a cooling device for cooling said supplied moisture; and (F) a humidification control device programmed to control said heating device and said cooling device such that when said detecting device detects lack of humidification, a humidification process is repeated alternately, the humidification process comprising: heating of moisture in said fuel cell stack to a first predetermined temperature; and cooling of said moisture to a second predetermined temperature.
