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 【課題】運用コストに優れると共に、燃料電池を迅速に暖機して早期に車両走行を開始できる車両用燃料電池の暖機装置を提供する。【解決手段】燃料電池４ａを冷却するＦＣ冷却回路１６と２次電池３及び充電器３１を冷却する充電補機冷却回路１８とを接続路５０ａ,５０ｂを介して接続し、切換弁４８ａ,４８ｂ,４９ａ,４９ｂの切換に応じて互いに連通可能とする。２次電池３の充電中において切換弁４８ａ,４８ｂ,４９ａ,４９ｂの切換によりＦＣ冷却回路１６と充電補機冷却回路１８とを連通させ、２次電池３及び充電器３１が発生する熱により加熱された充電補機冷却回路１８の水を接続路５０ａ,５０ｂを経てＦＣ冷却回路１６に移送して燃料電池４ａを暖機する。【選択図】図２
