Summary
Anion exchange membrane water electrolysis promises to combine the strengths of the two established routes to hydrogen - the performance of proton exchange membranes and the cheaper materials of alkaline systems. Getting there requires membranes with high hydroxide conductivity, low gas crossover and long service life, which are difficult to satisfy at once. This study reinforces terphenylene anion exchange membranes with electrospun polybenzimidazole, using a nanofibre mat to supply the dimensional stability the ionomer lacks.

The polybenzimidazole mats were spun on a Linari Engineering system at 20 kV, with a needle-to-collector distance of 10 cm and a flow rate of 0.4 ml/h. The paper does not name the model; see our range of electrospinning systems.
