My last chemistry class was a long time ago, so this might be a dumb question. What's the difference between combining with oxygen and burning?
- hoelle 17y agoIn a chemical sense, no difference, but fire is complicated. Check out Wikipedia articles on Redox, Radicals, Combustion, etc. Fuel cells are cool because they grab electricity straight from the freed electrons as the fuel is oxidized. More efficient than using the heat to make steam to power a turbine to spin electromagnets, your typical power plant.
