In 2010 this website had a competition for a fuel cell. see here
I wonder who won it and whether they can give us some feedback as it would be interesting for those that caravan a lot on rallies or sites without EHU.
Very expensive considering the wattage they produce.
I can only assume, as the technology progresses, prices will fall & by 2050 (when I will be celebrating my 71st birthday) we will all be camping with them!
In fact, by then they could well be old technology, who knows. We may even be camping on other planets
According to the EFOY literature, the 1600 uses around 0.9L of high purity methanol per kWh produced. A 10L methanol fuel cartridge could be used to generate around 11.1 kWh. The fuel cartridge costs £51.60 (if you can actually find anywhere that stocks them), so the cost per kWh of electricity generated is about £4.65. Wow!!!
Whilst the literature mentions that the EFOY 1600 uses about 0.9L/kwh produced, but doesn't mention that the energy content of 1L of methanol is about 5Kwh/L - so the efficiency of the fuel cell is only a little over 20%.
It also claims that no harmful emissions are produced and elsewhere that it is environmentally friendly. Methanol (CH3OH) is a hydrocarbon and CO2 is a product of combustion - so these claims don't really stack up either, especially when the efficiency is so low.
I don't see any real reason why anyone should go out and buy one of these. It's expensive to buy. It's very inefficient. Fuel isn't readily available and is about four times the price of petrol. Definitely a product for the "Early Adopter"s amongst us.

Not impressed.

TBH I think your figures are way off beam otherwise they would not be manufacturing them. There are stockists all over Europe and the UK as many motorhomes have the fuel cell fitted. The refill can be obtained for less than £40 for 10 liters.
I also have a spreadsheet from someone that is currently using a fuel cell and his figures do not stack up against what you have stated.
Fuel Cell Costs Per Day (excluding initial capital purchase of EFOY)
Outcome of Fuel Cell Evaluation Trial 2008 2011
Methanol Cost Per Day £1.11 £1.58
Gas Per Day £0.75 £1.30
Total Cost Fuel Per Day £1.86 £2.88
Site EHU & Gas Per Day 2008 2011
EHU per day CC&C site £3.50 3.55
Gas Per Day £0.36 £0.65
Total Cost Fuel Per Day £3.86 £4.20
A agree it is not a cheap set up unless you rally a lot and use a lot of non EHU pitches as it will take you about 4 - 5 years to break even. However if you take out the initial set up cost, then it is cheaper and better even than solar panels.
If you used all the normal 12v appliances in the caravan plus your satellite receiver and TV you would use approximately 3 litres of methanol every 7 days.

So, which figures are way off beam?
The cost I quoted came from the first result from Google (keywords: efoy,methanol,cartridge) - see here: http://www.campervanstuff.com/shop_stuff/index.php?mod=product&id_prd=1066
I've now found another that is cheaper - but not much and it doesn't affect the economics significantly. Even at £40 for 10 litres, electricity generated would still cost nearly £4/kwh. The comparison you quote isn't fair or realistic. A 16amp hookup is capable of supplying a load of up to 4kw - over 60 times greater than the Efoy 1600. You are not comparing like with like.
There are very few dealers for the methanol cartridges in the UK. My nearest is around 40 miles away - just as well I don't live in Scotland because there is only ONE stockist in the whole of the country - Cookstown Caravan - and the search facility in their online accessory shop finds no reference to either Efoy or methanol!!
