@lumen.potassium hydroxide,sodium hydroxide by far the best.sodium carbonate(washing soda),sodium tri-phosphate also excellent.make them concentrated.alkaline electrolytes are necessary.its like a fuel cell without air.you can use blackened nickel anode with rough etched copper cathode(copper not brass or bronze) and copper connecting wires in sodium hydroxide but be careful,air contamination corrodes the copper rapidly.you have to be certain that all surface metallic oxides and traces of oxygen present have been completely chemicaly reduced by the hydrogen before sealing.you must let the system rest a day or two under H2 to saturate the system,load it,before sealing.

@lumen.i forgot,you must thoroughly rinse nickel after the plating process.do not dunk it into alkaline electrolyte straight from the plating bath.rinse thoroughly first.to blacken silver or copper use them as an anode first in an sodium hydroxide electrolyte bath with a graphite cathode for a minute of two,then swap polarity and cathodize them until H2 bubbles stream off them hecticly.

.i,l post a photo after.

So where's your photo liar?

Just wondering.

Profitis,
  from the evidence you have provided, and from what is available online, it seems that your understanding of concentration cells is incorrect.

http://en.wikipedia.org/wiki/Concentration_cell

A concentration cell is a limited form of a galvanic cell that has two equivalent half-cells

The picture of the cell you are describing here has only one cell with two electrodes in it:

Perhaps the device you describe does work as you suggest, but it doesn't look like it's a 'concentration cell' - because there is only 1 cell - hence no concentration gradient.

Regards, Tim

here@sarkeizen,without furballs in the way.see,you was lying,your book doesnt have my quote on page 304 :-)
