“…A significant advantage of Alkaline Fuel Cell (AFC) technologies is the capability to use more abundant, inexpensive, and non-platinum catalysts [27]. While the air containing oxygen is fed across the cathode electrode, the fuel (H 2 ) is supplied over the anode.…”

“…Only highly purified hydrogen and oxygen can be used, the cost of which imposes a severe limitation to applications other than space [71]. Inorganic materials such as layered perovskite-type oxides such as LaSr have been used as the electrolyte in the alkaline fuel cell, but the study of these new inorganic electrolyte membranes is still in its infancy [27].…”

Fuel cells have lately received growing attention since they allow the use of non-precious metals as catalysts, which reduce the cost per kilowatt of power in fuel cell devices to some extent. Until recent years, the major barrier in the development of fuel cells was the obtainability of highly conductive anion exchange membranes (AEMs). On the other hand, improvements show that newly enhanced anion exchange membranes have already reached high conductivity levels, leading to the suitable presentation of the cell. Currently, an increasing number of studies have described the performance results of fuel cells. Much of the literature reporting cell performance is founded on hydrogen‒anion exchange membrane fuel cells (AEMFCs), though a growing number of studies have also reported utilizing fuels other than hydrogen—such as alcohols, non-alcohol C-based fuels, and N-based fuels. This article reviews the types, performance, utilized membranes, and operational conditions of anion exchange membranes for fuel cells.
