nickel hydroxide as electrode

[sucahyo]

Hello,

I read that some patent suggest the use of nickel for electrode. Anyone ever use pure nickel as electrode for HHO generator?

I do some experiment yesterday, using nickel hydroxide extracted from NiMh batteries. The other component is:
- two big 1.5 volts batteries.
- water added with a tea spoon of salt
- cable
- stainless steel pan

It only produce very small non released bubble in a minute in a spoon. It will produce a lot continuously released bubble using nickel hydroxide. It only produce bubble when it get negative current though.

if it is in a battery, it should be a good electrolyte, given it doesn't react with the water in a bad way.

Batteries use potassium hydroxide as the electrolyte.
I would get rid of the salt and use that.

I see, I didn't know about that, thanks for the info. Too bad already throw the rest of the batteries away. For how many days can the electrolite form the battery be used for HHO generator for 100cc engine?

I plan to use this nickel hydroxide in my generator. I wonder why I never read anyone use it. It produce bubble much much more than spoon stainless steel that I also tested. The spoon only produce some very small bubble on it's surface in a minute, while the nickel hydroxide release continuous bubble. It will also produce gas even when using single battery. It will still release gas using spring water on two battery.

I wish someone can test how nickel hydroxide with PWM and NaOH/KOH, compared with 316L grade steel.

If more bubble happen just because of this nickel hydroxide have same rating as 316L grade steel, I would still be using this metal since for me those bubble generation seems to be enough.

Maybe I should test Lithium Ion next.........

Nickel, Paladium, and Platinum which are all in the same column of the periodic table have one thing in common.
They all absorb many times there own weight in hydrogen.  I believe Paladium absorbs 3000 times it's weight in hydrogen.
This is why they have been considered as a way to safely store hydrogen for use in cars.
They are quite expensive as well, much more expensive then stainless steel.
