Ok guys here is the design I spent a ton of time and money working on:




(one note, the white shims are only shown to show detail that will not show up in a picture of a black shim. Also they look a little warped but that is due to the fact they are a soft flexible material used for an experiment production shims are hard plastic)

As you can see the design is actually very simple but very effective at limiting current leakage. By eliminating the holes in the plate that are exposed to solution, current leakage is significantly reduced. Is it totally eliminated? NO. The channels still provide a path for current leakage to take place but increases the distance (resistance).

My goal with this design was to make something that would be very efficient but relatively inexpensive to build. As such I will be offering the parts for sale for the following prices:

Shims $3each
Gaskets $3.50each
Power plates $4.50each
Plates $4each
Endplates $15each

That would put the price of a 7 plate cell at:
Shims $3 x 7
Gaskets $3.50 x 8
Power plate $4.50 x 2
Plates $4 x 5
Endplates $15 x 2
Total $108 + shipping and the cost of hardware.

As for MMW, let's say a conservative 5.5. I am not a big fan of advertising MMW's as everyone will measure differently.

If anyone is interested in some PM me.
