It occurs to me that if you wanted to run backup generators on veggie, that you could tap some of the waste heat from all the lieberts with a desuperheater and keep the veggie as hot as you liked for no net energy cost... :)

Technically fuel cells don't burn the fuel; they rely on a chemical process that is 
rather like a battery except that it relies on a continuous supply of fresh fuel
to supply hydrogen atoms. The fuel cell has a catalyst which strips electrons
off the fuel, and those flowing electrons are electricity.
 
Unfortunately, most fuel cells run very hot (600 C with molten carbonate) or
use noxious chemicals (sulphuric acid slurry). But a lot of work is being done
into developing fuel cells that run at low temperatures and which are not so
fussy about the fuel that you feed them. One company that has interesting
commercial products right now is Acumentrics:
