Fuel Cells – Alkaline Fuel Cell | Anion-Exchange Membranes

This article will discuss the use of alkaline anion-exchange membranes, the high-pH equivalents to the better-known acidic proton-exchange membranes in fuel cells. Chemical fuel cells operating with hydrogen, carbon- (e.g., alcohols such as methanol), boron- (e.g., sodium borohydride), and nitrogen-containing fuels (e.g., hydrazine) will be examined and the best performances found in literature will be reported. The use of anion-exchange membranes in microbial fuel cells (biological electricity generating systems) will also be discussed.
