ABSTRACT:
A fuel cell is provided for improving the starting performance at low temperatures. The fuel cell includes a cell structure in which an anode and a cathode are provided on either side of a solid polymer electrolyte membrane. The fuel cell may include a first cooling liquid passage and a second cooling liquid passage independent of the first cooling liquid passage. Cooling liquid is heated by an external heating device and supplied to the second cooling liquid passage.
