Development of sulfonated FEP–Nafion hybrid proton exchange membranes for PEFC

Recent Development of Polymer Electrolyte Membranes for Fuel Cells

“…Composite membranes containing organic materials having a sulfonic acid group often show higher methanol permeability and proton conductivity than do composite membranes containing organic materials without a sulfonic acid group because the sulfonic acid groups on the fillers can provide additional transport channels for methanol and protons. − All these composite membranes do indeed have reduced methanol permeability because fillers block the methanol transport channels and increase the channel zigzag. But only a few modified Nafion membranes have demonstrated sufficiently low methanol permeability to offset the reduction of proton conductivity.…”

A review of the performance and analysis of proton exchange membrane fuel cell membrane electrode assemblies

“…Nafion, used as the solid polymer electrolyte in PEMFCs, is the most common and available product. However, different solid polymer electrolytes have been developed, such as sulfonated FEPNafion hybrid membranes [16], PFSA-ePTFE composite membranes [17], and membranes utilizing the addition of microporous materials together with Nafion for improved strength [18,19].…”

Effect of preparative parameters on the characteristic of poly(vinylidene fluoride)-based microporous layer for proton exchange membrane fuel cells

“…However, the prohibitive cost of the PEMFC in conjunction with the problem of low reliability and durability presently are the major obstacles to its commercialization [1][2][3]. The performance and cost of a PEMFC are critically dependent on the electrocataytic activity of the noble metal platinum (Pt) catalyst [4][5][6], as well as on material selection, fabrication processes and performance of its various components, such as proton exchange membrane (PEM) [7][8][9], gas diffusion layers (GDL) [10][11][12] and bipolar plates [13][14][15].…”
