Type Structure Advantag e Disadvant age Chart: Proton Exchange Classification Perfluorosulfonic acid Non Fluorinated Composite proton exchange perfluorinated proton exchange membrane membrane proton exchange membrane membrane Consisting of a Fluorocarbon Hydrocarbon Composite carbon nitrogen main based, carbon groups, usually membrane chain and an ether chloride containing proton composed of branch chain with compounds, or conducting groups modified sulfonic acid groups aromatic side materials and chains perfluorosulfonic acid resin High mechanical Low cost, grafting Low cost, low Improved strength, good of proton link pollution, mechanical chemical stability, exchange groups high mechanical performance, high conductivity, in the side chain strength improved water high current density structure can transmission and at low temperatures, improve proton distribution and low proton conductivity within the conduction resistance membrane, and reduced internal resistance of proton exchange membranes The increase in Short lifespan and Poor chemical High technical temperature leads to poor stability: and thermal requirements for poor proton performance at stability; Low preparation conductivity, which is room temperature proton prone to chemical degradation and high cost at high temperatures is inferior to perfluorosulfonic acid proton membranes conductivity Figure 2Classification of Proton Exchange Membranes Existing and Under Development in the Market According to the calculations, demand for proton exchange membranes in the four fields of hydrogen production from electrolyzed water, hydrogen fuel cells, vanadium flow batteries and iron chromium flow batteries will reach 867000, 1691000,3147000 and 16702000 m2 square meters totally from 2023 to 2026, the market size is expected to reach 25 billion yuan by 2026.
