important technologies including fuel cells. Neutron studies untangle the complex dynamics in an anion exchange membrane when employed in a fuel cell setting. Fuel cells generate electricity from an elect ... of fuel cells, there is increasing focus on designs based on so-called anion exchange membranes (AEMs) that allow OH - ions to pass through. ...
