GENEPAX recently in Osaka Prefecture held hall council technical conference to introduce a water-fueled fuel cell system, "WES: WaterEnergySystem". The system to a fuel supply to the air for the very air power can not discharge CO2.

The basic principles of electricity and hydrogen-fueled fuel cell the same. The company is the MEA (membrane electrode then fit) is the most prominent feature of containing water can be broken down into hydrogen and oxygen to make the material. Did not disclose the details, but the company said: "MEA skillfully uses water from the well-known way to obtain hydrogen" (GENEPAX Jie, chairman, president Pyeongtaek). Close to the principle of metal hydride with hydrogen to form water, but is characterized by sustained for a long time to produce hydrogen from water.

As a result, only the battery unit of water and air, hydrogen without modification and high-pressure hydrogen tank. Moreover, MEA has not only the use of special catalyst, such as rare metals of the platinum usage in the past with the fuel cell system is basically the same.

In addition, different from the methanol fuel for direct-methanol fuel cell (DMFC), the fuel cells do not produce CO2, fuel is therefore highly unlikely, led by the CO catalyst for the deterioration (of poisoning), is expected to extend the life span. In life, the completion of the trial system from the 1-year, in the future continue to be the accumulation of data.

Conference demonstrated the power rating of 120W and 300W fuel cells and fuel cell systems. 120W fuel cell group in the demonstration, the ThinkPad T40 battery  pack from the initial dry water pump began pumping power after the closure, for passive type of work. Power generation fuel cell stack voltage to 25 ~ 30V. From the group of 40 fuel cell units that series, a unit of power for more than 3W, the voltage of about 0.5 ~ 0.7V, current of about 6 ~ 7A. From the unit as part of the response to 10cm × 10cm speculated that the power density of more than 30mW/cm2.

On the other hand, 300W fuel cell system is the active type, pump water and air supply. In the demonstration, in addition to charging lead-acid Latitude D820 battery , lighting and power supply to the TV, the staff Wugang car technology is still small electric vehicle "Reva" The installation of cabin baggage 300W fuel cell systems, as power supply was driving . The company is scheduled to adopt the actual 500W system, but the material development of the MEA has not yet been completed, so replace it with 300W fuel cell group.

On the future development, GENEPAX expressed the hope to the family of electric vehicles and the supply of 1kW-class power generation system. For electric vehicles, the idea of generating system will not be alone for the driver, but as a generator for battery charging for electric vehicles. At present, the cost to about 2,000,000 yen, post-volume production, 1kW can be reduced to below 500,000 yen. The company said that if the manufacturing costs to achieve, with solar home systems to compete
