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. 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. © The Electrochemical Society.

In a method of preparing a ruthenium-containing catalyst on a non-conductive metal oxide support comprises dissolving one or more ruthenium precursor compounds in an liquid organic polyol, combining the thus obtained solution with (a) nano-powder(s) of one or more metal oxides in a ratio of moles metal oxide(s) to moles ruthenium atoms in the one or more ruthenium precursor compounds of about 0:1 to about 6:1, the metal oxide nano-powder(s) having a surface area of from about 5 to about 300m

Alkaline membrane fuel cells designed with silver cathode catalysts include a catalyst layer comprising silver metal nano-particles and an anion-conducting ionomer. The silver nano-particles are mixed with a solution of the ionomer to form a catalyst ink that is applied to an alkaline membrane to form an ultra-thin cathode catalyst layer on the membrane surface.

A catalyst coated membrane (CCM) for an alkaline fuel cell having OH-ion conducting catalyst layers and a membrane, wherein the ionomer throughout the entire CCM is cross-linked in one chemical step including cross-linking within the membrane and within the catalyst layers, thus enabling simultaneous chemical bonding across the interfaces between the catalyst layers and the ion conducting membrane.
