Alkaline Membrane Fuel Cell (AMFC) Materials and System Improvement - State-of-the-Art

Abstract

In the last few years, developmental work on anion conductive membranes for AMFC has significantly increased and several polymer chemistries have already been tested at very small AMFC scales. On the other hand, scarce work is being done on anion conductive ionomers, and just a very few groups are working on electrocatalysts for the electrodes of this technology. From the limited materials developed for this technology, peak power density records of almost 200mW/cm2 were already achieved. Non-published data suggests that the actual power densities that can be achieved with today's state-of-the-art anion conductive polymers are even much higher. With the latest and most advanced developed materials, AMFC stacks providing 2kW power output were already developed. During this presentation, the state of the art on AMFCs will be reviewed, and current challenges in the development of new materials will be briefly discussed.
