Has anyone ever see any articles of fuel cells being powered by LPG to allow batteries to be float charged. I realise if it takes a converter to get the AC to run a smart charger may be a little inefficient but I'm prepared to cope with that. If of course it will charge a 12 volt battery direct all the better. The idea is not new but from what I have seen it may not be worth the effort but I'm prepared to have a look at it. Thanks, Brian

There's a write up in the last grey nomad times

Here is a 100w version but seems to be no website for them now that I can find.

They claim to have an LPG reformer to convert 11kg of LPG to 20,000 ltrs of Hydrogen which doesn't seem to add up to me as it is about 115% efficient with no calculation for loss of energy from heat (calculating off BTU's if that's the correct method, I'm no expert but that's how I normally calculate efficiencies), but without seeing it I couldn't say for sure.

It's an interesting theory and I would love to see a working example if anyone has one.

Thanks for that GST. Saw that article shows that some people are looking outside the box. What I'm looking for is something that will deliver a heap more power than that but thanks for the pointer Regards Brian

Thanks Mccanic, there have been a few attempts over the last few years to put all this together but in the main it's not been successful. As you mentioned some of the figures they come out with just don't add up. Anyway I'll just keep looking and see what happens. I'll let you know if I find something that looks like it might be something Regards Brian
