A Water Energy System
Genepax intends to provide 1KW-class energy generation systems for use in electric vehicles and houses.
Instead of driving electric vehicles with this system alone, the company expects to use it as a generator to charge the secondary battery used in electric vehicles. The fuel cell system competes with residential solar cell systems.

The following memo has been posted:
- Thank you for visiting our website.
- We at GENEPAX have strived to develop new technologies to enable environment friendly energy systems, to mitigate environmental risks such as those posed by global warming. The systems that we have proposed have received warm words of support from many people. However, we have yet to overcome the many obstacles we face in the current world, to bring our systems to market. Moreover, the costs of development have become very large. As our resources are very limited, we need to retrench and reassess our resources and our development plans at this time, and we are accordingly closing our website.
- We express our deep gratitude for the supportive messages we have received. We hope that you will continue to be supportive of efforts to develop cleaner and more environment friendly energies, and we will continue to strive to develop systems to preserve our environment.

How it Works
The main feature of the new system is that it uses the company's membrane electrode assembly (MEA), which contains a material capable of breaking down water into hydrogen and oxygen through a chemical reaction. With the new process, the cell needs only water and air, eliminating the need for a hydrogen reformer and high-pressure hydrogen tank. Moreover, the MEA requires no special catalysts, and the required amount of rare metals such as platinum is almost the same as that of existing systems. It is expected to have a longer life because catalyst degradation (poisoning) caused by CO does not occur on the fuel electrode side.
The water energy system 1 has a cell in which a fuel electrode 3 and an oxygen electrode 4 are faced with each other through a catalyst 2 same as a general fuel cell. The fuel electrode 3 is formed by carrying platinum on a sintered body of fine powder of zeolite, coral sand, and carbon black, the oxygen electrode 4 is formed by carrying ruthenium on the sintered body of fine powder of zeolite and carbon black. Electric power is generated under normal temperature by supplying pure water 5 to the fuel electrode 3 and air to the oxygen electrode 4.

1KW-Class Generation Systems
120W fuel cell system
The voltage of the fuel cell stack is 25-30V. Because the stack is composed of 40 cells connected in series, it is expected that the output per cell is 3W or higher, the voltage is about 0.5-0.7V, and the current is about 6-7A. The power density is likely to be not less than 30mW/cm2 because the reaction area of the cell is 10 x 10 cm.
300W fuel cell system
The 300W fuel cell system is an active system, which supplies water and air with a pump. In a demonstration, Genepax powered a 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 coppartment of a compact electric vehicle "Reva" manufactured by Takeoka Mini Car Products Co Ltd, and the vehicle was actually driven by the system.
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.

Pure water is supplied to an anode-side electrode plate 47 from a pure water supply groove provided on the surface of the partition plate through pure water supply holes 41c to 45c from outside of the clamp plate 41, and air taken in from an air intake formed at outer peripheral end surface of the separation plate is supplied to a cathode-side electrode 48 from an air supply groove provided on another surface thereof. A desired power generation capacity can be obtained by adding and connecting in series electrode joint bodies 42 and partition plates 44."

- Genepax Water Car: Too Good to be True? Yeah - It is actually possible to make a car look like it runs on water without breaking the first law of thermodynamics.

- FuelCell Japan - item (74).
June 12, 2008, at the Osaka Assembly Hall.
Genepax unveiled a fuel cell stack with a rated output of 120W and a fuel cell system with a rated output of 300W. In the demonstration, the 120W fuel cell stack was first supplied with water by using a dry-cell battery operated pump. After power was generated, it was operated as a passive system with the pump turned off.

"A blog revealed the critical metals used in the Genepax fuel cell.
Ruthenium Platinum and some coral sands
As we all suspected, the car we saw in the Reuters news video was running from it's charged batteries, not direct electricity from the fuel cell. Nevertheless, getting 300 watts of power from a metalic reaction with water is a worthy accomplishment. We now wait to see how long the metals last before they deteriorate into useless oxides or other inert compounds."
Price Point Not Favorable
I voted not top 100. Even if this works (I'm somewhat skeptical short of more proof), the product is not economic at either their current manufacturing cost ($18,522 for 300 Wp or $61.74 per Wp) or their target rate ($5,000 for 300 Wp or $16.67 per Wp). The use of water for fuel is just a curiosity because the cost is greater than that of traditional fuel cells AND their fuel costs.
I would also want to know about their stack life. Stack life is a huge problem for all fuel cells - many of which have lives measured in hours (typically 6 months to 4 years of continuous operation. For this product to achieve grid parity, it would need a 20 year stack life at 9.5 cents per KWH grid prices or 10 years at 19 cents per KWH.
Genepax response: "The stack life is not yet in data but we imagine our stack would last as long as other fuel cell stack. We have data of other fuel cell in public and it lasts 40,000 hours." Best regards, Jun Onishi
Recieved June 18, 2008;
"Please excuse me for my English ability.
1) About the water fueled car
We are not car manufacturer. We have invented generator (fuel cell) which produces heat and electricity from pure water. We had loaded the generator into electric vehicle sold in the market for demonstration. Information of milage is not formal data.
2) Investment / Stock exchange
We have no schedule to go public and do not accept any outside investment.
We are looking for cooperation, if possible public company, to distribute our "Water Energy System" locally.
4) Press release for Foreign Press
We will only invite media (reporters from magazines, newspaper, tv programs).<br. NO schedule for public presentation at this time.
5) More information
We are working on English version of our website and hoping to update fully by next week. FAQ is under translation and will be updated soon.<br. Still we are not going to announce the core part of our technology.
6) How can I buy one?
Genepax has no schedule to sell our technology as a product to private customer.
7) Real? Fraud?
We understand invention is always attacked by critism.
Since we cannot inform our core technology, we are announcing the factual data taken by 3rd party with public trust. Our testing will start soon and hoping to announce the performance clearly.
We are very sorry if this email did not answer your question.
We check all the emails and try our best to answer in FAQ.
Again, thank you for your precious comments and we will do our best."
