Aligned for renewable power

Alkaline membrane fuel cells can operate using nonprecious metals as catalysts, but rely on polymeric membranes with high hydroxide conductivity and alkali-resistance, which are hard to find. A new membrane is now reported comprising ferrocenium cations in magnetically aligned domains with an excellent combination of these properties.
