PROBLEM TO BE SOLVED: To provide a battery pack including a fluid channel which has a function to support a battery and, when a gas is generated by the battery, to prevent a gas from spreading.SOLUTION: A battery pack 1 includes: plural battery laminates 2 constituted of plural single cells 20 which are integrally laminated with each other; a fluid channel 42 which is formed between the battery laminates 2 to allow a fluid to flow for cooling the single cell 20; an air blower for supplying the fluid to the fluid channel 42; and plural heat conduction plates 5. The heat conduction plates 5 are connected to an outer case of the single cell 20 each constituting the neighboring battery laminates 2 so as to transfer the heat, and a part thereof constitutes a part 50 to be cooled positioned in the fluid channel 42. The battery pack 1 includes a channel formation member 4 which has a partition wall for supporting the heat conduction plate 5 to partition the fluid channel 42 as a path isolated from the periphery of the outer case of the single cells 20.SELECTED DRAWING: Figure 3

    【課題】電池からガスが発生した場合にガスの拡大を抑えるとともに、電池を支持する機能を有する流体通路を備える組電池を提供する。【解決手段】組電池1は、複数の単電池20を積層してそれぞれ一体に構成される複数の電池積層体2と、電池積層体2の間に設けられ、単電池20を冷却する流体が流れる流体通路42と、流体通路42に流体を流通させる送風機と、複数の熱伝導板5と、を備える。熱伝導板5は、隣接する電池積層体2のそれぞれを構成する単電池20の外装ケースと熱移動可能に接続され、かつその一部が流体通路42に存在する被冷却部50を構成するようにそれぞれ設けられる。組電池1は、熱伝導板5を支持する隔壁を有するとともに、流体通路42を単電池20の外装ケースの周囲とは独立した通路として区画形成する通路形成部材4を備える。【選択図】図3
