Genepax Co Ltd explained that the technologies in its new fuel cell system " were used, water energy system (WES), " why water is used as fuel and non-CO2-serie.

The system is possible the production of energy, particularly by supplying water and ventilates to the fuel and lucht-elektroden, and the company said place in Osaka auditorium during the press conference, 12 June 2008.

The basis for electricity induction mechanism of the new system is that of a normal fuel cell seems on hydrogen as fuel. According to Genepax the most important characteristic of the new system, which the company ", is; use de-elektrode (MEA), a material that concerning the partitioning of water in hydrogen and oxygen by means of a chemical response able is.

Although the venture concerning the details, " revealed; followed with a process confessed, with a view to hydrogen produce water to the MEA, " the company ' said Kiyoshi Hirasawa; s-president.

This process the mechanism has been supposedly produced similar with hydrogen by means of a response of the Metallhydrids and water. But it is expected in comparison with the current method, the new process that hydrogen water for a long time to produce, thus the company. With the new process must cell only water and ventilates and eliminates the need for reformer hydrogen and oxygen through a chemical reaction. Moreover the MEA are no specific catalysts, and the required quantity of rare metal if platinum has been said almost the same as those of the existing systems, Genepax.

In contrast to direct methanol fuel cell (DMFC), the methanol as fuel uses the new system radiates niet-CO2. Moreover it according to the expectations a longevity is, because the catalytic reduction (poisoning) does not square caused by Co on the fuel magnet acts. Considering there has been only something more than one year since the prototype automobile the company has been of plan more collect data concerning the life span of the product.

On the conference, Genepax a fuel cell pile with a taxable capacity of 120W and a fuel cell system with a taxable capacity of 300W. Demonstration cell pile of fuel 120W first supply of water had been used by dry an cell batterij-aangedreven pump. After energy it has been generated, has been processed, whereas a passive system with the pump abstellte.

This time was it the voltage 25-30V. Because the battery of 40 warrants, which are integrated for their part, is that each cell question 3W or higher, the tension has been approximately expected 0.5-0.7V and current is approximately 6-7A. Energy compactness is no less than probably 30mW/cm2 is, because the response of the cell of 10 x 10 cm.

Meanwhile the cell system of the fuel 300W is an active system, water and ventilates, with a pump provides. In demonstration Genepax drove televisie-en reduction equipment, with lood-zuur-batterijen, which he was used at the expense of the system. Additionally, the system 300W must in the luggage space of a compact electric carrier " necessary, Reva" produced with the car product Co Ltd Takeokamini and the volume had been really floated by the system.

Genepax first plans to develop a system 500W, but became the material for MEA at the moment and finished supply, concerning the top, then he formed a system 300W.

Although the future of the venture of plan is, 1kW-class in electric and in the houses production for use to supply. In place, electric bray with this system to control, only already the venture expects this place to use as a generator to other battery(secondary), in the electric makers uses.

Although the production costs z.Z. of ¥ 2,000,000 (US $ 18522) can be brought back, to ¥ 500000, or lower as Genepax with mass production follows. The company believes that fuel cell system with residential solar cell can systems compete with if the costs at this level can be brought back.
