Any thing about Full Cells get me to Googling.
At least I found One that is actuly forsale at Max Power/full cell. Perhaps its not quite ready for prime time. At 5000 euro it delivers 100A dc power per day.
It uses a 4.4kl proprietary cartrage of Methanol. So the efficiency of the fule cell is lost in acquiring the cartrage. There are more issues, but I am out of time at the moment.
