Abstract:

Environment protection and environment-friendly energy development are very important for human and society. Proton exchange membrane fuel cell (PEMFCs) have attracted much interest due to their high energy conversion rate and pollution-free in recent years. The electrospun nanofibers show the specific properties, such as a high specific surface area, high porosity and fully interconnected three-dimensional network structure, and are one of feasible candidates for PEMFCs applications. The composite proton exchange membrane containing aligned nanofibers has the ability to achieve high proton conductivity, low fuel permeability in fuel cell and good chemical, thermal, and mechanical stabilities. In this paper, PEMFCs are introduced firstly, then, starting from the composite proton exchange membranes of different ionic polymer matrix, the application and mechanism of electrospun nanofibers in different kinds of ionic polymers such as Nafion, sulfonated polyimide (SPI), polybenzimidazole (PBI) and sulfonated polyether ether ketone (SPEEK) are introduced in details, and the main problems and the development trend are also discussed.

Key words: proton exchange membrane fuel cell, ionic polymer, electrospinning, nanofibers
