I TORE ITS GUTS OUT!  \m/

Yeah, I should have done this a while ago.  Too much instability, that stuff was soup!  This cells primary purpose was to help me determine if increasing the mass of the electrodes(specifically the anode) would generate significantly more power.  So aside from more copper in the electrodes, everything now resembles no.9, no.9 was built half mud and half dry substrate, and no.9 is using extra copper rings on the cathode to keep it pressed against the substrate.

Top half dry now!

Some extra copper to keep the cathode in contact while the lid is closed.

I'm also thinking about punching a few holes around the cell just above the substrate line so heavy gasses can escape without choking out the cathode first.

It was reading 232mv .83ma when I closed the lid about 40min ago.

It is still stabilizing and sorting itself out but this is already improvement.
