Ion solvating membrane
WebThe KOH-doped membranes present a large affinity for water and gradually replace the acid hydrogens in the imidazole rings with K. Only at KOH concentrations above 4 mol L −1 are “free” KOH molecules present in the membrane structure, along with a small fraction of glycerol molecules. These behaviours impact on the membrane dimensions.
