Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing.

[0024] As shown in the figure, the outer cylinder 10 in the present invention is a fixed sealed hollow cylinder, the inner cylinder 9 is coaxial with the outer cylinder, and micro-channels of different sizes are distributed on the wall, the aperture is 0.01-1.0 mm, and the porosity 50% to 80%, the spiral blade 11 is fixed on the outer wall of the inner cylinder, leaving a small gap with the outer cylinder, similar to the structure of the blower wheel and the outer wall, the inner cylinder is fixedly connected with the transmission shaft 5 through the connecting rod 4, Driven by the drive shaft, the inner cylinder and the screw blades 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 from the raw material gas pipeline 1 and directly enters the electric stack 13. The ...

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.

Description

technical field [0001] The invention relates to a proton exchange membrane fuel cell, in particular to a humidifying device for the proton exchange membrane fuel cell. Background technique [0002] The fuel cell is equivalent to an electrochemical cell, which directly converts the chemical energy of the fuel into electrical energy, with an efficiency as high as 40-60%. Proton exchange membrane fuel cell is a kind of fuel cell, because of its low operating temperature, it can be started at room temperature. Proton exchange membrane fuel cells use hydrogen as fuel, and hydrogen is adsorbed and dissociated into hydrogen ions at the anode of the battery. The electrolyte membrane is a special membrane that only allows hydrogen ions to pass through. Currently the most widely used is the fluorinated sulfonic acid membrane, in which hydrogen ions are converted into hydrated protons (H 3 o + ) form, migrate from the anode to the cathode, and react with the oxygen or air in the cat...
