Re: E FOY Fuel Cell Generator

Well, $10K to get a 90w system (nominal output, per literature, 2200w hours / 24) just doesn't seem like it makes too much sense. And, that doesn't include fuel.

Am I missing something?

Re: E FOY Fuel Cell Generator

I think the fuel costs would need careful research.

After ten minutes of research I notice the 5 liter fuel bottle has a capacity to generate 5.5 kWh of electrical energy.

And it looks like the Comfort 140 model will produce 1.7 kWh per day at a 12v 6amp output to charge a recommended 60-240 Ah battery bank. At about 140 Ah per day that sounds like a fairly common daily usage on a modest cruiser.

Assuming as such then a 5 liter bottle would last about 2-3 days. Appears to be a cumbersome 6 amp battery charger that runs out of fuel every three days to me.

The question is, at what cost and how to manage supply of fuel. Which by the way appears to be methyl alcohol or naphtha. Don't no if the bottles are proprietary or how hard to refill.

That's what I got after ten minutes, but I'm not intrigued by any means.

I could be wrong yet again, but seems to me a solar array producing the same amount of daily energy would be much more cost effective and simpler to use and maintain.

Rated output 90w
Fuel cartridge comes in 10 liter
Methanol consumption is 1.1/100 Ah

Re: E FOY Fuel Cell Generator

So if one used the rated output daily, with that model, the 10 liter bottle would be empty in 4-5 days.

Where does one purchase methanol? at what price? At usage rate of 10 liters per week to source, seems problematic.

I've never had a need for methanol, so I'm clueless.

But wouldn't a couple hundred watts of solar be a better idea? and more green? 180 Ah of solar per day doesn't seem as problematic to me.

Re: E FOY Fuel Cell Generator

As a backup, and not used daily, that does change the scenario somewhat.

Had not even considered shipping the fuel, with added cost and hassle of shipping a flammable liquid. Personally wouldn't want to do that too often.

Hopefully one wouldn't have to use it.

Seems like more trouble than it's worth, and I wouldn't expect this product for achieve much wide spread use.

They should try selling the units for pennies on the dollar to get them out there and make the money off proprietary fuel supply. That worked pretty well for ink jet printer makers for a while.

Re: E FOY Fuel Cell Generator

I just don't see much use for a product that requires a fuel source that is not readily available in the places that I'm going to be.

Re: E FOY Fuel Cell Generator

Handy for race boats as lightweight power backup (vs. a heavy diesel genset or engine). However the energy density of the fuel is less than diesel so after some point in time the diesel genset is lighter.

Solar is tough to beat over the long haul. Nigel Calder has often used an amortized average cost of $4/kWh for energy produced by diesel on the average yacht. That's figuring in the cost of eventually replace the diesel engine. He's put figures that calculate that some boat solar installations can actually pay for themselves in around a year.

Lots of variables to be sure. Anyway, I have heard of some racing boats using the E-Foy units.

Re: E FOY Fuel Cell Generator

This thread is rather old since it's debut--- Anyone out there actually using Fossil Fuel visa vi E-FOY System or anything of its kind? I would really like for one of their sales REPS do the MATH for us and explain 1) How + 2) Fossil Fuel is cheaper/greener than Solar/Wind generation? Is that too much to ask? Anyone know if the IRS is still giving away TAX deductions for BUYING either a Solar System or Fossil Fuel System?

Defender has these units for sale:

http://www.defender.com/category.jsp...985&id=1848741

$59.99 plus shipping for the 10 liter (2.5 Gal) fuel cartridge, that is only $24 a gallon methanol. I will pass up going green in this case.
