In　this　paper,　a　fuel　cell　integrated　heat　management　system　model　is　constructed.　The　residual　heat　of　fuel　cell　stack　is　transferred　to　power　battery　through　liquid-cooled　pipeline　to　improve　the　working　environment　temperature　and　the　performance　of　power　battery　at　low　temperature.　The　simulation　results　show　that　the　residual　heat　of　the　stack　can　obviously　increase　the　temperature　of　the　power　battery　at　different　ambient　temperatures,　and　the　temperature　of　the　power　battery　can　be　increased　more　effectively　by　the　arrangement　of　liquid-cooled　pipes　in　the　inner　part　of　module　group　than　in　the　upper　and　lower　parts　or　on　the　left　and　right　sides.　©　2018,　Editorial　Department　of　Journal　of　Tongji　University.　All　right　reserved.
