Highly hydroxide conductive ionomers with fullerene functionalities†
Abstract
A novel ionomer was designed that will not poison the catalyst in alkaline fuel cells, by incorporating for the first time N-methyl pyrrolidine-C60 cation in polymeric anion exchange ionomers. The resultant fullerene-based anion exchange ionomer shows an extremely high hydroxide conductivity (182 mS cm−1) at a low cation concentration (0.62 mmol g−1).
