Development of air metal hydride battery (AMHBAT)

Project Details


Development of air metal hydride battery (AMHBAT).
The aim of the project is to develop a rechargeable air hydride battery to be used in electric vehicles (EV). The operating principle of an air metal hydride battery is rather simple: Water is split into hydrogen and oxygen as the battery is charged. Oxygen is released to the atmosphere and hydrogen is stored in the negative electrode which is made of a hydrogen storage alloy similar to those used in nickel metal hydride batteries. On discharge the process is reversed, and stored hydrogen recombines with atmospheric oxygen to form water. The air hydride battery has been studied since 1988 at Helsinki University of Technology (HUT) and the state of the art is a prototype batteries (24 V, 360 W) made by HUT and the Finnish company Hydrocell.
The project involves 5 European universities and 6 industries. It is Supported by the European Community (JOULE, fourth framework programme).
