In 2013 more than 200 papers focused on AEMs, electrocatalysts, and also on small lab scale AMFC preparation and testing were published. Leading academic groups in PennState, Surrey, Wuhan, NREL (etc…) are making interesting progress:

Hickner (Tew et al., JACS 2012) works on fundamental
development of new anion conducting polymers for
AEMs. Some first polymers already showed practical
conductivity, but poor stability (hours-level).
Varcoe (AMFC workshop, Surrey 2013) keep making
progress using a simple radiation-grafted process to
functionalize commercially available films. Initial
reasonable IECs were already obtained in their ETFE-
based membranes.
