I have two of the Efoy 2200 Commercial Fuel cells. One mounted and wired into my 2008 GU Nissan Patrol the other as a test bed for work. The fuel cell is magic. Only problem appears to be the starting price of close to $11,000. Per unit. The unit is quiet gives off very little heat and a small amount of water.

Supplier indicated to Only use the branded Methanol, ultra pure and certified. Given the small amount we go through I won't risk a cheaper
Alternative. Bit like buying LPG I guess, at least I know it's pure

Got more time now.
System is about as dangerous as carring Petrol in an approved fuel container. However I would say better in so much as the Ethanol Fuel container is designed specifically to not allow you to come in contact with the fuel and is approved for transport.
Having said that I work for a company that is very safety conscious and we have been through the process wit the RTA now the RMS. I have however plumbed in the unit so that both the water drips outside and also the off heat. Given that I work in Central West where the ambient air temperature is sometimes 50 C I have added a fan to allow the off heat to also vent externally by manual switch. The unit itself is realy light 8Kg only so the 10lL Fuel container weights more that the Fuel Cell itself !
The unit works with my portable 60w 2 off fold up Solar Panels. And a second 100Amp Hour VLRA Deep cycle battery. We went for the EFOY so we could set it up and forget the unit it would simply turn on when required to keep our Emergency Communications Patrol "topped Up" and ready to go at a moments notice. We had the requirement to operate on the top of a hill often within a National Park, where we are not allowed to use a Petrol Generator or a Diesel Genset.
The unit works well fro our application I will post some photos when I get the chance

So the EFOY has been working for 270 Hours. It is quiet and automatic. I would comment that it only used a small amount of Fuel whilst the documentation say for my 90Watt unit it uses 90ml per hour. However I would comment that it is only using this amount when the unit is in full operation. That is to say not using this amount at idle, not during startup but just when it is in full charge mode.
The unit itself comes with comprehensive instructions for operation of the unit and fitting the unit. I made up an adaptor plate from marine plywood and covered it in marine carpet. To this I bolted the steel mounting plate this mounting plate allows the Fuel Cell to be mounted in two directions you need to ensure where the "off Heat" will flow out. This is very little heat, but it needs managing in a confined space like a car or truck. I have mine surrounded with equipment but because I addressed the heat and h2O issue during fitment I haven't had any problems. The other observation I would make is that it can run at ANY time unlike a Generator that has to be turned on or Solar Panel that has to be deployed and set up, doesn't work at night.

So 90W of power may not seam a lot but 24/7 with low noise running continuiously is quite sufficient to run our Satellite gear, 65L Engel, lights, 4 40w UHF radio and all the other gear.

hi peter h2
interesting topic you haven't actually said but i assume by the equipment been used it generates 12v power ?
what is the expected life of this $11000 plus set-up cost outfit and
is it a sealed unit or is it repairable down the track or a throw-away unit ?
cheers

Yes 12V NOT 240V It also a 12v Battery for the unit to work.

The unit is sealed so I guess it has to be returned to the supplier. I would have to check my paperwork on the warranty but mine is for 2 years and 20,000Hours operation.

The unit comes with all the cabling and all the Plumbing hoses etc, So it should for the price. They have over 25,000 units in Non Commercial units in operation in the US and Europe. From what I can see you should be able to get the units re-furbished. Mine in my GU is operational for about 4 hours a month without an incident. We have had one incident of 3 days where we were fully reliant on the unit to provide the power. We were only able to use our 120w Solar array for on of thes days only.In this 3 day period we used 1000ml of Methanol. We are paying $38 for 10L of Methanol. We use both the 5L and the 10L fuel containers not the 25L We pick-up or fuel from the NSW distributor in Kirrawee NSW. You need to pick-up, or you will be hit for "Dangerous Goods" transport. Like fuel

Hi Peter,

As Mazcan has said - very interesting bit of gear. Pity about the price, but no doubt that will come down with time, production quantities and competition. Anyone interested will find a bit of detail here.

Cheers

At the moment for 20 litre -205 litre we pay $2.00 per litre of methanol for our race car much cheaper per pellet of 4 x 205 drums but with that fuel consumption even a 20 litre is a good buy compared to gas or a petrol generator!

The Fuel from the supplier is ultra pure and certified, with the special fittings so you don't come into contact with the fuel. I would also suggest that It's sealed and ultra pure for a reason and you would invalidate the warranty. For the small amounts we use I'm happy to go with the certified product. If you we're running a really big system I guess the price and amount of fuel might be an issue.
As I mentioned before the unit is nearly silent, We have an ARB roof top tent on our GU, and even with the barn doors open at night it really hard to here the unit when it is on, even with the silence of the outback.
The unit also has a remote control/ display that comes with it and a container of "service fluid" You do not have to have the remote plugged in for the unit to work automatically. If however you build you unit in somewhere where you can't see the LED status lamps you can install the remote, it's simple CAP 5 LAN cable and then have the remotes display somewhere easy to read. It has LED status lights, and a liquid crystal backlit display that you can cycle through, status, indicating machine status, charge rate in AMPs, unit serial number and hours of operation. It also indicates when the fuel tank is empty. You can get a module that allows automatic changeover from an empty fuel tank to a new one, It can also SMS you to let you know for a remote backup site, that you need to go change the tank. You can also harness several fuel cels together for more Watts output, and have a single controller.

My GU has an uprated alternator from standard 100ah to 120ah, for my starting battery I use and Optima yellow top it's a D31. For the "house" battery having wrecked 4 of the same yellow tops, I now have a Lifeline VLRA battery, 100ah. Problem in the GU is the aux battery position is that is is right beside the Turbo and the battery gets Cooke. had I known this I would not have fitted it there at all and made space in the back. We did for a period have a third Yellow top Optima in the rear, this is where the EFOY fuel cell has been built in. It's like having a battery that never goes flat. We also have a CTEK 240v to 12v charger that chargers both battery's when mains is available. The EFOY is set up to charge both battery's. You can set the "start" charge threshold, and the cutoff threshold, in the setup.
So mine is an EFOY pro 2200 it produces 2160 Wh/day nominal power 90w 12v/24v, weighs 8.95 kg. on charging at 12.3 v off at 14.2v.
We had some concern about it operation during 4wd as the info states max 35 degrees around the roll axis temporary max 45 degrees and max 20 degrees around the lateral access.
We also had some concerns around the operating temperature, hence my design of forced cooling fan, as the specs states-20c to +45c.
None of these have been an issue so far, we will keep an eye out as the ambient temperature, rises for summer. That said, it is in the rear cabin of the GU, so whilst driving its air conditioned, and not operating

$11,000 seems a lot of money for just 180 AH per day. There is an outfit in the USA which supplies replacement alternators for popular 4WDs that will produce 200 amps at idle. That's 200 AH for one hour at idle. I recall they cost about $700 plus freight. I think most petrol 4WDs will use about 1.5 litres per hour idling under that load; less for diesel.

Add in a smart regulator at about $500 and a lithium iron phosphate battery of 400 AH (350 usable) from a golf cart at about $2,700 plus some cabling for a total cost of about $4,000.

The battery would hold its charge for months. I am thinking about such a setup for my own van, plus a solar array, with charging from the car as a backup instead of a gennie. Would that be a better solution or is there a horrible downside that I haven't thought of?

Downsides are (a) noise from car, same as noise from gennie issue, (b) alternator might provide 200A but your batteries are unlikely to charge at anywhere near that rate.
But probably still a good, cheaper, solution.

hi
idling a diesel engine for long periods to gharge batteries with 200amp alternator would oil up and also glaze the cylinders
might be a quick way of charging but not good for the motor

Hi Peter,

These fuel cells seem to be a great idea, but also look to be cost prohibitive at this stage for the average person. But go back 10 or so years ago and one could say the same for solar cost. Give it a few years and hopefully economies of scale will have fuel cells on par with solar :)

Cheers
