The invention discloses a proton exchange membrane fuel cell humidifying and positive electrode tail gas treating device and belongs to the technical field of fuel cells. The device mainly comprises an inner barrel, an outer barrel, a connection rod and a transmission shaft, wherein raw material gas flows through an outer cavity; positive electrode tail gas of the fuel cell enters an inner cavity; the inner barrel can rotate along with the transmission shaft; a small multiporous bulge is arranged on the inner wall of the inner barrel, and an extremely thin catalyst layer is arranged on the inner wall; a small hole is formed in the wall of the inner barrel and is communicated with the outer cavity. The device can treat the positive electrode tail gas and alleviate pollution to the environment and potential risks such as combustion and explosion; meanwhile, heat carried by the positive electrode tail gas and heat and water which are produced by positive electrode tail gas reaction are fully used for humidifying
