<p>PROBLEM TO BE SOLVED: To provide a power supply device for vehicle which is made to have small temperature difference among a plurality of cells forming a row of cells in order to improve a cell output at low temperature. SOLUTION: A first duct part 36a of a heater duct 36 is installed at one end of a row of cells 28 constructed by laminating a plurality of cells 46 in the direction of thickness, by the above, the cold air from outside is blocked at a first duct 36a of the heater duct 36, and as a lowering of the temperature of the cells 46 on the side where first duct 36a of the heater duct 36 is formed, is restrained, the temperature difference through a plurality of cells 46 constructing a row of cells 28 is reduced. Here, the air is filled in the first duct 36, and as the heat conductivity of the air is smaller than that of solid heat insulator like glass wool, the temperature difference through the cells 46 is kept smaller than the temperature difference when a conventional heat insulator is used.</p> |
