High-performance alkaline ionomer for alkaline exchange membrane fuel cells

An alkaline ionomer synthesized with a cross-linker, featured with long aliphatic chains of alkyl groups and inherent diamine structures, not only exhibits a high ionic conductivity (60.5 mS cm(-1)), but also significantly boosts the peak power density of H-2/O-2 alkaline exchange membrane fuel cells to 342 mW cm(-2).
