Example Embodiment

[0023] The present invention will be further described below in conjunction with the drawings.

[0024] As shown in the figure, the outer cylinder 10 in the present invention is a fixed and sealed hollow cylinder, the inner cylinder 9 is coaxial with the outer cylinder, and the wall is distributed with micropores of different sizes, the pore diameter is 0.01-1.0 mm, and the porosity The spiral blade 11 is fixed on the outer wall of the inner cylinder, leaving a small gap with the outer cylinder, which is similar to the structure of the blower wind wheel and the outer wall. The inner cylinder is fixedly connected to the drive shaft 5 through the connecting rod 4, Driven by the drive shaft, the inner cylinder and the spiral blade rotate together. The raw material gas enters the cavity 2 between the outer cylinder and the inner cylinder through the raw material gas inlet 7, and goes out of the raw gas pipeline 1 to directly enter the stack 13. The tail gas of the stack enters the i...

Abstract

The invention discloses a humidifier for a proton exchange membrane fuel cell, belonging to the technical field of fuel batteriecell s. The humidifier mainly comprises an external cylinder, an internal cylinder, a spiral blade and a transmission shaft, wherein the spiral blade is fixedly arranged on the outer surface of the internal cylinder, a micropore iss are arranged in the wall of the internal cylinder, and the internal cylinder is connected with the transmission shaft by a connecting rod. The humidifier is used for humidifying before raw material gas of the proton exchange membrane fuel cell enters an electric pile, and fully utilizing moisture and heat in tail gas, can adjust the pressure of the humidified gas, has the advantages of being energy-saving, high-efficiencyt, and convenient to adjust, meets the raw material gas humidifying requirement and the pressure requirement for entering the electric pile, the energy consumption and cost of a fuel battery cell system can be reduced and lowered, the volumsize is decreased, and the effects are obvious.
