Anion exchange membrane fuel cells (AEMFCs) transport anions through the membrane, converting chemical energy into electrical energy

To make the film, the scientists used a new method that combines the chemical bonds of two commercial polymers, poly-2,6-dimethyl-1,4- Phenyl ether (poly(2,6-dimethyl-1,4-phenylene oxide, PPO) and styrene-ethylene/butylene-styrene triblock copolymer (poly(styrene-b-(ethylene-co-butylene) -b-styrene, SEBS)

Professor Tae-Hyun Kim from Incheon National University, who led the research, said: "A similar attempt was made in previous studies to prepare anion exchange membranes (AEMs) by crosslinking PPO and SEBS using hydrazine as a crosslinking agent.

Films prepared by this method can be up to 10 μm thick and exhibit excellent mechanical strength, chemical stability, and electrical conductivity even at 95% indoor humidity

The new AEM has good development prospects
