Genepax intends to provide 1kw-class 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.


Keelynet suggests that the power is from Aquafairy technology in the June 21, 2008 news entry that links to 2 articles from 2006 - Fuel Cell for Mobile Phones and Docomo, Aquafairy develop water-powered fuel cell. Congress:Member:Robert L. Pritchett (June 22, 2008)

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.

Banal Fuel Cell?

First off, it has to make it through the laws of physics. Here it is going

to have problems.

More energy in than out is how I see it. This is not a miracle catalytic

device, but a banal fuel cell.

Joules in, joules out is the only thing interesting, all their beautiful

marketing where every word and each dot above the i have been masterfully

chosen is of no importance. If something is behind the facade, the first

thing to do is proudly hang out the measurement results. Until then, this

is bottom 1k, not top 100. Driving a small electric car around with fully

charged batteries before starting and a 300 Watt miracle device to

charge the batteries does not impress me.

Burning Metals!?

If their not fraud then they are probably corroding the metals in the cell. The options include aluminium, magnesium, chromium and zinc. It's an on demand hydrogen system. A mix would work best since some are exothermal and others are endothermal. My guess is aluminium, magnesium and sodium as the catalyst. They say the cell will last 40000 hours that's 4 years. I suspect it will be much less given the power out put described. I can do better with Al-foil and drain cleaner. However it should be remembered that the Japanese have several universities working on solar regeneration of magnesium oxide to metal. These guys may be betting on fast and easy solar powered recycling of the metal.

Even I'm looking at solar aluminium.

On June 16, 2008 Congress:Member:Robert L. Pritchett wrote Is it possible that Genepax is using this patented process to generate hydrogen power? No "chemical catalyst", but using 2 electrical circuits to generate orthohydrogen and parahydrogen.

On June 17, 2008 Congress:Member:Mark Anthony Dansie wrote

If you read carefully, it's running on fuel vapours, the Genepax is also a play on words, on translating the website you will see the unit is only 300wh, you would need 20 of them to run that vehicle and more than a litre of water.

With the steam reformation...its a very real technology, I mam working on a project using steam reformation of diesel and water at the moment...has a lot of promise for a bridging technology.

There is no free lunch. Water does not have useful chemical bond energy to apply to a fuel cell. All of the energy made available by hydrolyzing water with a metal and a catalyst is first stored by the industrial processes that prepare the refined metal. This is not new technology. It is another in a long string of reinvention of very: large, heavy, and expensive batteries. As mentioned above, hydrolyzing water using aluminum as the reducing agent and a caustic catalyst is the stuff of certain brands of drain cleaner. Use of dilute weak acids as catalyst was developed many decades ago by Boeing for ultra long shelf life emergency battery systems.
