Abstract
This paper presents new results which may constitute a breakthrough in the effort to develop fuel cells truly suitable for use in cars and trucks. For decades, researchers have known that the alkaline fuel cell (AFC) is much cheaper to make, more efficient and more durable than the more popular PEM fuel cell; however, "carbon poisoning" (either from CO2 in air or from contaminants in reformed methanol) causes big problems in the kind of oxygen-hydrogen AFC commonly used in space. This paper reports successful tests of a technique for coating the electrodes with polystyrene which, in conjunction with older common-sense techniques, appears to solve the problem. This kind of design is applicable to cars run on hydrogen fuel, on reformed methanol or even direct methanol. Developing a test methodology was a major part of the work. A foreword by one of the sponsors at NSF discusses the larger importance of this work for energy security and the environment.
