Hydroxide Ion-Conducting Polymers. The Holdcroft group synthesizes and studies hydroxide ion-conducting polymers for alkaline water electrolysis, fuel cells, and CO2 electrolysis.
We designed a new sub-class of polymers, C2-sterically-protected polybenzimidazoliums and polyimidazoliums, which are exceptionally stable under highly caustic conditions at elevated temperatures: J.
