Anion-exchange membranes are used in alkaline fuel cells, a technology which allows for the production of power from hydrogen in impure gas streams. Very little is known about the microscopic processes behind the anion (hydroxide) conduction in these membranes. Level crossing studies with muons will allow some investigation into the dynamics of the grafted polymer chains, which contain phenyl groups (which interact with muonium to form radicals). These studies will yield information about the changing polymer dynamics associated with different humidities (and therefore different anion conductivities).
