PURPOSE:To restrict heat conduction from high-temperature reacting gas flowing in a pipe line to a container, and prevent a rise of container temperature by fitting a pipe line for supplying and exhausting the reaction gas to a battery housed container through a cylindrical pipe filled with the heat insulating material. CONSTITUTION:When a pipe line 9 for supplying and exhausting the battery reaction gas is fitted to a sealed container 7 in which a fuel cell 1 is housed, the pipe line 9 is inserted into a cylindrical pipe 11 concentrically with the cylindrical pipe 11 filled with the heat insulating material 20. The pipe line 9 is connected to the cylindrical pipe 11 through the heat insulating packing 14 interposed between the cylindrical pipe 11 and a flange welded to the pipe line 9, and a flange part 17 of the cylindrical pipe 11 is fixed to the outer wall of the container 7. Consequently, the pipe line 9 for supplying and exhausting the reaction gas is fitted to the battery housed container 7 through the cylindrical pipe 11 filled with the heat insulating material 20 to eliminate direct contact to the container 7. Heat conduction from the high-temperature gas flowing in the pipe line to the container 7 is thereby restricted to prevent a rise of surface temperature of the container, and heat loss can be reduced. |
