Cheap and effective fuel cells are achievable using alkaline anion-exchange membranes, according to a UK chemist. The technology offers the potential to produce power more efficiently and cleanly than combustion methods.

...

John Varcoe, from the University of Surrey, has been developing alkaline anion-exchange membranes (AAEM) for many years. AAEM fuel cells are similar to the highly studied proton-exchange membrane (PEM) fuel cells but the membranes are designed to transport hydroxide ions instead of protons. AAEMs are less expensive to make than PEMs and can be used with cheaper electrodes.
