| 1. An installation structure of a gas sensor which detects concentrations of gas circulating inside piping, the installation
structure comprising:
a catalytic combustion method hydrogen gas sensor,
an opening provided in an inner wall of the piping, and the gas sensor comprises a gas inlet opening which opens inside of
the gas piping directly,
wherein said gas sensor is installed to the piping in a condition where said gas inlet portion does not protrude from the
inner wall surface of the piping,
wherein the piping is coupled to a cathode-side of a solid polymer electrolyte fuel cell such that the gas circulating inside
the piping is discharged from the cathode-side of the solid polymer electrolyte fuel cell, and
wherein said gas sensor is installed at an upper portion of the piping relative to the direction of gravity.
