PROBLEM TO BE SOLVED: To provide a warm-up device of a vehicular fuel cell excellent in operation cost, and capable of starting vehicle running at an early stage by warming a fuel cell quickly.SOLUTION: An FC cooling circuit 16 for cooling a fuel cell 4a and a charging auxiliary machine cooling circuit 18 for cooling a secondary battery 3 and a charger 31 are connected via connection paths 50a, 50b, so that they can be interconnected in response to changeover of changeover valves 48a, 48b, 49a, 49b. The FC cooling circuit 16 and the charging auxiliary machine cooling circuit 18 are interconnected by changeover of the changeover valves 48a, 48b, 49a, 49b while charging the secondary battery 3, and the fuel cell 4a is warmed by transferring the water of the charging auxiliary machine cooling circuit 18, heated by heat generated from the secondary battery 3 and the charger 31, to the FC cooling circuit 16 via the connection paths 50a, 50b.SELECTED DRAWING: Figure 2
