PIPING CONNECTION STRUCTURE OF FUEL CELL

PROBLEM TO BE SOLVED: To provide a piping connection structure of a fuel cell that can prevent the generation of dew condensation around supply piping that supplies reaction gas to a fuel cell. SOLUTION: In the piping connection structure of a fuel cell, a hydrogen gas is supplied in a decompressed state from a hydrogen gas tank 11 provided outside a housing box 1 into a fuel cell unit NU arranged in the housing box 1 through a supply pipe 8. An elastic boot member 15 for covering the supply pipe 8 is fitted between the surrounding at the downstream side of a joint part 14 to the fuel cell unit NU of the supply pipe 8 and the surrounding of an insertion hole 10 of the housing box 1 into which the supply pipe 8 is inserted.
