New Fuel Cell System 'Generates Electricity with Only Water, Air'
Jun 13, 2008 19:30
Kouji Kariatsumari, Nikkei Electronics

[...]
The system can generate power just by supplying water and air to the fuel and air electrodes, respectively, the company said at the press conference, which took place June 12, 2008, at the Osaka Assembly Hall.

The basic power generation mechanism of the new system is similar to that of a normal fuel cell, which uses hydrogen as a fuel. According to Genepax, 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.

Though the company did not reveal the details, it "succeeded in adopting a well-known process to produce hydrogen from water to the MEA,"...

I think they are being rather 'circumspect' with the truth on that one...

... chemical reaction. Genepax, the Japanese company unveiled the 300W eco-friendly car with a demonstration on 13 June 2008 in Osaka, Japan. The cost of the energy generator (not including the car), once it gets into mass production, is said to be about $5,000 (US). The technology is explained in this diagram. The big question is, what is the cost of the the metal hydride that is consumed in the process?

OK, the simple non-technical translation is that they are using a consumable BATTERY to chemically generate hydrogen gas from water that is then used to power a hydrogen fuel cell to then drive an electric motor.

For that example, a more accurate description is that the metal-hydride BATTERY is the "fuel". The water and hydrogen are just part of the power transmission system.

An analogy is to claim that a coal-fired steam train is "water powered"!

I wonder if we'll ever wage war over metal-hydride batteries,

Is hydrogen and metal-hydride exhaust better than petrol exhaust?

I wonder if the millions dead in the middle east would prefer civilians of the world using something other than a peaked out energy source which just happens to be beneath them.

What kind of car do you drive, ML1?

Not over those batteries but very possibly over the resources that make them.

Is hydrogen and metal-hydride exhaust better than petrol exhaust?

That depends...

The immediate 'exhaust' is water and heat. However, you also have the chemical waste from firstly making the battery and then for disposing of the remains after it is consumed.

That is a BIG problem of various ideas for going electric or hydrogen fueled: Usually, you are just moving the pollution to 'somewhere else' rather than at the vehicle. Also, even worse, the overall system is often less efficient that what presently (pollutingly) is being used.

A good (but costly) idea that appears to have been abandoned is to break down oil into hydrogen and CO2 at the oil well head and pump the CO2 back down into the well to hide it away for a long time. Dangerous but plausible but so far not even going to be tried anywhere.


I wonder if the millions dead in the middle east would prefer civilians of the world using something other than a peaked out energy source which just happens to be beneath them.

I think that they have more of a problem firstly with their own internal (religious) politics than with that...


What kind of car do you drive, ML1?

Diesel with intercooled turbo. Power when needed but efficient for cruising.

I may well be trying it with some locally produced biodiesel.


However, by far the greatest saving that I've made is by no longer commuting to work each day.

Cheers,
Martin

In the future, I think that they will be a lithium-ion battery with some advances in Polymers and manufacturing.

Small turbo Diesel to extend the range and to charge the battery if away from electrical hook-up.

I figure 1300-1500 cc with 2 intercoolers should produce around 100 horsepower and maybe up to 200 foot lbs of torque.

Should be enough for a light aerodynamic car of about 2500 lbs.

Why don't they use lithium-ion now?

How much electricity does it take to separate hydrogen from water?

http://www.youtube.com/watch?v=AmYHEnXBguI


How much hydrogen is required to run a cell car?


I gotta look these numbers up.


And why some fancy cell when we can power our existing engines with hydrogen?

Tesla Motors uses Lithium-Ion:

http://www.teslamotors.com/

I think they approach 200k on price tag, though. Maybe thats the problem with li-ion?


New fuel cells being introduced because too much hydrogen needed for power compared to cell? Or more money in it for cell manufacturers since everyone would need to buy one?

Jun. 13 - Japanese company Genepax presents its eco-friendly car that runs on nothing but water.

The car has an energy generator that extracts hydrogen from water that is poured into the car's tank. The generator then releases electrons that produce electric power to run the car. Genepax, the company that invented the technology, aims to collaborate with Japanese manufacturers to mass produce it.

SOUNDBITE: Kiyoshi Hirasawa, CEO, Genepax.

Here is a link to a company that says what your link says is impossible yet they are going to sell converters for your car to run on Hydrogen or gas...http://www.switch2hydrogen.com/h2.htm Curious what people think of this?

Still impossible.

First, you still need to overcome two fundamental foundations of philosophy and science:


You've also still got one hell of a fight with all of thermodynamics and entropy!

I think that adds up to "impossible".


It will work, but not for any useful net gain. At the very least it very likely will not work as advertised...

In your dreams?

In the home,we can make the roughly and simple one,because it was effortless.The problem is unsafety(contaction with oxygen in the air,Hindenburg disaster of 1937),efficiency(energy input),storage(characters of hydrogen's particles) and cos.But for the big company,they can deal with high tech which come up with many concepts and prototype under researh such as Biological production,Solar Thermochemical and Thermochemical production etc.I saw many of the article about it,also conduct an experiment at the school(simple one).Talk is cheap without work.
This type of energy is not conflict with the energy prinsiple,because it is storage of sunlight energy. I was thinking,what the logical change occur as a single atom even basic particles related energy?The universe create the all element,simple to complex one,should we using the most natural and efficiency way,adds with mathematicy calculation.What the natural forcing us(ex.When we burn gaseline,the very little of mass converted into energy,and the byproduct should have tiny increase of their mass) ?The energy converted to mass,get little workforce and turn back to pure energy,limitless?Maybe the most advanced civilization able to harnessing this kind of naturaly and recycleable energy-mass converted based on the universe's principle.

As far as carrying around a bunch of bottles of Hydrogen, I think it is quite dangerous.

The water fuel (some type of electrolysis at work), can work, if you have enough room for extra power (batteries, probably several of them...) that you can charge at home or wherever, when the vehicle is not in use. IMHO.
