A perfluorinated anion exchange membrane with a 1,4-dimethylpiperazinium cation demonstrated enhanced hydroxide ion conductivity.
The membrane also exhibited a better water uptake than a typical hydrocarbon anion exchange membrane with the same cation. When tested, the membrane showed a remarkable stability of over 30 days in 2 M KOH at 60 °C and good fuel cell performance. Work is ongoing to investigate the attachment of more basic cations to further enhance the hydroxide ion conductivity, fuel cell performance and long term stability.
