COOLING SYSTEM OF FUEL CELL AUTOMOBILE

To provide a fuel cell automobile including a fuel cell and a heating component capable of solving a problem that when a fuel cell cooling flow path and a heating component cooling flow path are connected in parallel, a non-return valve is required to prevent backflow, and the non-return valve acts as a resistance and the pump drive power increases undesirably.SOLUTION: A bypass flow path that bypasses a series flow path that connects a fuel cell cooling flow path and a heating component cooling flow path in series and a heating component cooling flow path is provided. With this, a non-return valve is not required and the pump drive power does not increase undesirably.SELECTED DRAWING: Figure 1 【課題】 燃料電池と発熱部品を備えている燃料電池自動車において、燃料電池冷却流路と発熱部品冷却流路を並列に接続すると逆流防止用の逆止弁が必要となり、その逆止弁が抵抗となってポンプ駆動電力が無駄に増大する。【解決手段】燃料電池冷却流路と発熱部品冷却流路を直列に接続する直列流路と、発熱部品冷却流路をバイパスするバイパス流路を設ける。逆止弁が不要となり、ポンプ駆動電力が無駄に増大することがない。【選択図】図１
