Fuel Cells that Run off Ethanol or Sugar Possible?

Click For Summary
SUMMARY

Fuel cells, specifically Proton Exchange Membrane Fuel Cells (PEMFC), primarily operate using hydrogen (H2) and oxygen (O2). While direct usage of ethanol in fuel cells is not feasible, reforming ethanol into methane (CH4) is a viable alternative. The discussion raises the question of whether sugar can be reformed for fuel cell use, although its efficiency is questionable due to its oxygen content. The chemical reaction for sugar decomposition is provided as C6H12O6 → 2 (C3H6O3) + Energy.

PREREQUISITES

Is it possible to make fuel cells that run of ethanol or even sugar? :confused:


Is it a good idea? Why/Why not?
 
Computer science news on Phys.org
PEMFC fuel cells and a few others can only run on H2 and O2. Solid oxide fuel cells can run on CH4, CO and H2.

Although direct usage of ethanol is not possible, usage by reforming it to convert it into methane is possible. I don't know whether reforming of sugar is possible or not.
 
Sugar probably wouldn't be very efficient because it caries oxygen, but I thought the following formula was interesting

C6H12O6 ---> 2 (C3H6O3) + Energy
