PROBLEM TO BE SOLVED: To provide a power supply which can surely communicate a gas exhaust tube with a gas exhaust path of a cell module and has a high rigidity. SOLUTION: A gas exhaust pipe 68 is made of polypropylene. This way, in case the gas exhaust pipe 68 is pressed to the side of a cell module 12 in a state that the position of the gas exhaust pipe 68 is decided to set a grommet 102 rightly above the gas exhaust tube 30 in order to insertion-couple a grommet 102 inserted into a long hole 73 of the gas exhaust pipe 68 and a gas exhaust tube 30 of a cell module 12, the gas exhaust pipe 68 is not crashed, and so, the grommet 102 and the gas exhaust pipe 68 can be surely insertion-coupled. Also, since this gas exhaust pipe 68 has higher rigidity than a rubber gas exhaust pipe, the rigidity of the power supply as a whole is also improved. |
