WARMING-UP SYSTEM OF FUEL CELL

PROBLEM TO BE SOLVED: To provide a warming-up system of a fuel cell capable of preventing degradation of starting performance of the fuel cell mounted on a mobile body in a low temperature environment. SOLUTION: The mobile body is provided with an electric heater 17 for heating the fuel cell, and a warming-up heating medium circulation means 16 for circulating a heating medium heated by the electric heater through the fuel cell 1. A power supply unit 24 for supplying power to the electric heater 17 for heating the fuel cell 1, and a controller 20 for performing heating control on the fuel cell 1 with the electric heater 17 are disposed outside the mobile body. The controller 20 performs heating control on the fuel cell 1 with the electric heater 17 based on a temperature detecting signal from temperature detecting sensors 18, 19 which detect the temperature of the fuel cell 1.
