Japanese Start-up Plans Hydrogen Fuel Cell For 2014
angry tapir writes "A Japanese start-up says it has finessed a technology that could finally make consumer-grade fuel cells a reality. If successful, the company, Aquafairy, would create a business where many much larger companies have failed. Prototypes of the company's hydrogen fuel cell technology are on show this week at the Ceatec exhibition in Japan where the company's president, Mike Aizawa, said he hopes the first products will be on sale next year."
Their specs indicate lower specific energy than lithium ion batteries, combined with a huge base unit. The end result is that you're going to end up with something that is heavier and bulkier than existing USB lithium ion batteries, making it just another gimmick.
I could see them having some success in much larger scale applications, though (like three orders of magnitude).
Right. Because 3000psi hydrogen gas makes a much more convenient storage medium than a plastic gallon jug of methanol or ethanol.
Hydrogen Fuel-Cell systems are interesting but I suspect the whole idea doesn't work. There's still a problem of how you're actually suppose to produce the hydrogen for cheap. Imagine developing a combustion engine while you haven't even worked out a process to drill or refine oil for the engine. Besides, I'm not sure folks would want to buy fuel for their laptop rather than just plugging it in for few pennies of electricity.
Nah, you don't really want a pony. They take up a lot of room and smell funny.
And you can't charge your iPhone with it.
Faster! Faster! Faster would be better!

Set up a treadmill attached to a generator and put a salt lick at the front of the treadmill. Problem solved.

It's cheaper to make hydrogen from fossil fuel directly, though getting it to fuel-cell-worthy efficiency is a very tricky process - even a hint of carbon monoxide destroys fuel cells.
Splitting water has the advantage of changing production rate within seconds, making it ideal for exploiting periods of low electricity demand and thus low electricity price.
A Swedish company already did this, they call it "myFC" and it's powered by a "puck" of hydrogen. Wether it's useful, I have no idea.

Sure you can! You just accumulate the methane it produces, purify it, compress it, and burn it in a natural gas generator. No problem, it would only take one wave of the magic wand to get all that working . . .

Most commercial hydrogen is produced by steam reforming natural gas, not electrolysis.
They key to a hydrogen economy (Ugh, buzzword/phrase) isn't the production of hydrogen but its storage. 3000 PSI (20.68Mpa) cylinders aren't appealing to safety advocates or consumers and other forms of storage haven't panned out. Plus the energy needed to compress hydrogen to high pressures begins to make the overall process much less efficient. Without a method to densely store hydrogen safely, effectively and efficiently, liquid fuels (including liquefied gas) will remain the preferred choice.
It's always been possible to use metal hydrides to, in effect, store and release hydrogen relatively safely. I'm guessing this is another attempt to do the same thing. The problem is economics. Even when stored this way, hydrogen simply does not have the volume density to compete with other forms of energy storage. It is a promising technology that may ultimately prove useful if cheap liquid fuels actually do run out, but until then I have to be a little skeptical.
Nonaggression works!
A "large" unit that does 200 watts might be useful for trickle charging batteries on a RV to allow for some boondocking when the solar panels don't give enough power to keep the bank charged... but we already have technologies out that give a better energy/volume than what is stated.
Truma, an European RV appliance maker makes a fuel cell that uses propane. It makes up to 250 watts, which may not run an A/C, but it does a good job at keeping the batteries topped off, which is important because RV furnaces require electricity for the vent fans for the heat exchanger.
There is also the EFOY cell that uses methanol that is starting to be used in RVs in the US (Roadtrek E-treks), but it is still quite expensive. If it starts selling for a bit less, it will go a long way to keeping batteries maintained when a rig is stored or when boondocking.
With all the disadvantages of hydrogen (3600 PSI, while a propane tank will vent at 200 PSI), I'd give this a good start, but still needs work before it would have a real niche here in the US.
