Let see if I can make something from what you provided: Cell configuration has 2+, 1-, and 8N meaning +NNNN-NNNN+. If this is correct, I hope you are using a strong solution mix, because that configuration requires a strong mix. What electrolyte are you using? If you are using NaOH, use 450g per 1 gl. of distilled water or 1lb per 1gl. This is for brute force running, for KOH I would start with the same. If you still don't see any production increase the solution and make sure you have good connection to all the terminals.

You should see 10-15 amps usage initially, oh yeah mix the solution ahead of time and let it cool. DO NOT mix and then fill your system.

Electrode reactions: Zn --> Zn2+ + 2 e-

2 MnO2 + 2 NH4+ + 2 e- --> Mn2O3 + H2O + 2 NH3

The role of the NH4Cl is two-fold: to remove oxide from the MnO2, and to provide mobile ions. Thus it is both a reagent and an electrolyte

Thanks for you reply
Yes you are all correct
Iv tryed to use a little baking powder. Just for a bench
No good.
I will try to get some other Stuff koh (where to buy))?
What's the best confegration?for a small cell
Thanks for your help

you can get the stuff from the net, try AAA chemical they ship anywhere.

If you want decent electrolyte fast, you can grab Roebic crystal drain cleaner (100% NaOH) from lowes/home depot for about $10-$15.

You can get a 1lb. container of NaOH from ACE Hardware for just under $5.00.

Are you saying it doesn't work at all - no gas whatsoever? Because you should see some gas evolving with that configuration even just with tap water.

Your initial post does not provide enough info. How are you powering the electrolyser? Is it from 12 volts?
