Abstract:
The Alkaline Fuel Cell (AFC) is an electrochemical device that can convert the chemical energy of H2 directly into electrical current at relative low temperatures (60-250°C). In most studies in the literature, the catalyst used is Pt in AFC prototypes, but many researchers tried to replace the expensive platinum catalyst with another non noble metal. Membranes are typically composed of a polymer structures onto which are inserted fixed cationic sites.The first challenge for polymer chemists, membrane scientist and electrochemists is to fabricate AEM (Anionic Exchange Membranes) with a high OH- conductivity and excellent mechanical properties. This fuel cell is the most studied actually because show an economic reason, the electrocatalyst can be non-noble metal such as Ni, Ag, MnO2. The aim of this paper is to present the state of the art of physical - chemical characteristics of components and there achieved performances.
