Homemade Hydrogen Fuel Cell?

[Andrew7dg]

Ok, it is one of those stories where a friend of a friend made a homemade hydrogen fuel cell on his car. I don't know the complete details because the friend that I know doesn't know cars very well. He asked me how the system worked and I never heard of it. I guess from what I have heard, it is done with water, baking soda and a battery. It was hooked up in the car in the fuel or air system and now it get 40 mpg per gallon of gas with this technique.

I have never heard of this working or even heard/seen of this in any of the car forums. Unless I missed out on this somehow but usually these homemade gas saving techniques are full of shit...

Does anyone know of this or was this discussed in another thread that I don't know about?

It works. Get a garbage can, fill it with distilled water, pour in some baking soda, seal it off, pump it through a compressor into a tank, then you have compressed hydrogen. There might be a bunch of oxygen there too, I don't know.

That is not a fuel cell. That's just a little "free" hydrogen gas. Fuel cells require fancy metals and non-combustable oxidation blah blahbitty blah to make electricity. Very different.
