Incorporating a ruthenium complex into the backbone of a cross-linked polymer has led to the first metal-based anion-exchange membranes. The new materials could make fuel cells more efficient and less expensive, and might allow them to operate under a wider range of reaction conditions (J. Am. Chem. Soc., DOI: DOI: 10.1021/ja211365r).
