PROBLEM TO BE SOLVED: To provide an inflammable gas discharge pipe and system, which sufficiently controls both permeation of rainwater and outbreak of fire. SOLUTION: A hydrogen gas discharge pipe 10 is used for discharging hydrogen gas ejected from a power generator to the outside world. The hydrogen gas discharge pipe 10 comprises a pipe body portion 11 having the proximal end portion 111 communicating with the power generator and extending in the direction of antigravity, a portion 13 provided at the other end 113 of the pipe body portion 11 and extending while bending from the direction of antigravity, and a discharge portion 15 having the proximal portion 151 provided at the end 131 of the bending portion 13 and a discharge opening 16 located at the end 153 and opening to the outside world. The bending portion 13 bends from the other end 113 about 180°from the direction of antigravity and further bends in the horizontal direction before being connected to the proximal portion 151.
