If hydrogen fuel cells run on refined hydrogen gas and oxygen, and output only water and co2…?


category: Hydrogen Cars

Couldnt you use that outputted h2o, and seperate hydrogen and oxygen by electrosys or whatever, and find a way to refine that in teh automobile, and therefore have a source of renewable fuel?
but isnt getting that natural gas wasting a limited resource as well?
Thanks, you guys. All that really helped.

    Yes you can, but note that it is a very small amount of water that is given off, and to extract hydrogen by electrolysis is actually a pretty expensive project.
    The easier way they get hydrogen is by getting it from natural gas passed over a catalyst at a certain pressure and temperature.

    You need energy to separate the H form the O in water. Where that energy comes from may cause pollution (thermal plants burn coal, nuclear plants produce radioactive waste).

    baby steps
    were still in the developing stages
    a few universities are working on what your asking. UCSD and Standford that I know of but the returns are rather small and for now only used to slightly extend the run time. you should know these same groups are not working on new car engines but rather zero energy homes… ponying solar hydrogen fuel cells and new home designs into a complete system with out changing the way people live now…
    Standford is useing solar cells for the electrosys to extract hydrogen they think in ten years it will be ready for market
