Description
Technical Field
The invention relates to a proton exchange membrane fuel cell humidifying device with a self-regulating function, in particular to a dry air device for humidifying a cathode inlet by using tail gas exhausted by a fuel cell, which has compact structure.
Background
Proton Exchange Membrane Fuel Cells (PEMFC) have wide application potential and development prospect in fixed electric power application and transportation alternative energy sources and incomparable advantages of traditional power sources due to high energy density and conversion efficiency, low working temperature, quick start-stop response, small mechanical vibration and noise and no weather influence basically.
The proton exchange membrane fuel cell mainly comprises seven parts, two bipolar plates with gas channels have the functions of conducting current to form a passage and providing a flow field for reaction gas; two gas diffusion layers, which have the functions of supporting and protecting a proton exchange membrane and a catalytic layer and conducting electrons and gas; two catalyst layers, which have catalytic action and provide places for converting chemical energy into electric energy; electrolyte membrane (proton exchange membrane) -has the function of separating the cathode and the anode, blocking gas from electrons, and conducting protons. Fuel H when PEMFC is in operation 2 Passes through the anode gas diffusion layer from the anode gas passage to the catalytic layer of the anode, and is dissociated into protons and electrons by the catalyst in the catalytic layer. The proton and the electron reach the catalyst layer of the cathode and the O reaching the catalyst layer of the cathode through the proton exchange membrane and an external circuit respectively 2 The chemical reaction and the energy produced by the chemical reaction do work outwards, and the reaction product is water.
The proton exchange membrane is a core component of the PEMFC, and the performance of the proton exchange membrane directly determines the performance and lifetime of the cell as a whole. The performance of the proton exchange membrane is determined by the water content, and the proton exchange membrane has good proton exchange performance only under certain humidity, and the higher the water content is, the larger the proton conductivity of the proton exchange membrane is. However, under PEMFC operating conditions of high temperature (> 80 ℃) and low humidity (< 50%), the water absorption and proton conductivity of the proton exchange membrane is reduced by several orders of magnitude because it cannot retain water in the ion clusters. At present, various methods have been adopted to ensure the humidity of the fuel cell membrane, including modification of the proton exchange membrane and the catalyst layer, and one or more water retention or waterproof layers are placed between the gas diffusion layer (GDLa) and the catalyst layer, the most common and effective method is to add a humidifying device outside the fuel cell to humidify the reaction gas of the fuel cell, and generally use the external water source or the exhaust gas discharged from the cathode of the fuel cell as the humidifying gas, but both humidifying devices have the disadvantages of relatively complex structure and low humidifying efficiency.
