FuelCellToday writes: It is claimed the Water Energy System (WES) developed by Genepax can generate power by supplying water and air to the fuel and air electrodes. The basic power generation mechanism of the system is similar to that of a standard fuel cell. The main feature of the new system is that it uses a membrane electrode assembly (MEA), which contains a material that breaks down the water to hydrogen and oxygen.

Though the company did not reveal any more detail the company president said that they had "succeeded in adopting a well-known process to produce hydrogen from water to the MEA", similar to the mechanism that produces hydrogen by a reaction of metal hydride and water. However the company claims that compared with the existing method, the new process produces hydrogen from water for a longer time.

Genepax unveiled a fuel cell stack with a rated output of 120W and a fuel cell system with a rated output of 300W. The 300W system is an active system, which supplies water and air with a pump. In the demonstration, the company powered the TV and the lighting equipment with a lead-acid battery charged by using the system. In addition, the 300W system was mounted in the luggage room of a compact electric vehicle "Reva" manufactured by Takeoka Mini Car Products Co Ltd, and the vehicle was driven by the system.

In future Genepax intends to provide 1kw-class generation systems for use in electric vehicles and for residential applications. The production cost is presently about ¥2,000,000 (US$18,522), it estimated that it can be reduced to ¥500,000 ($5000) or lower if the company succeeds in mass production.
