Mr. G cell Project Page 1

8/7/08. At the suggestion of a member with the screen name "SeaMonkey", a cell was fabricated to his specifications. 10 plates, 3"x 6", wired +-+-+- etc. This is called a "low voltage" cell. SeaMonkey recommends operation at 2-3 volts, if I recall. As I did not have a DC to Dc adapter handy, a battery charger was set at 6 volts, and a Mr. G cell was run in series to give each cell approximately 3 volts. 3 tea. lye were added to one gallon water. All 10 plates were tested and using current, so no short was present. Amps consumed- a little under 3.
The results follow: With + at 10 plate cell and - at Mr. G cell- 3.76 volts on 10 plates, 3.49 on the G. With + at Mr. G cell- 3.73 volts on 10 plates, 3.38 volts on Mr. G cell.
My personal conclusion: The 10 plate cell has far in excess surface area. As is clearly seen, it passes current without producing gas. It was using more voltage than the Mr. G cell. I also tested using a lye solution of 6 tea. per gallon. Amps were 5, both cells produced slightly more hydroxy, but not noteworthy, especially the 10 plate. I was disappointed with the results, but that is not significant.
I am sure the 10 plate will perform well with more amps. But I fail to see a practical reason to use it, when another design is available which is vastly superior, and requires less material and space.

8/7/08. As you can see, production on this 10 plate cell
occurs primarily between the first two plates.
All plates were tested to be sure that they were actively passing and using current.
The cell was assembled with #10 stainless nuts, bolts, and lock washers.
The bolts are covered with nylon tube at various points for insulation, and larger tube was used for interior spacing, cut 1/8" wide. The alternating plate edges were covered with the same tube, cut with a slit, and slid on. This aids in separation and insulation.
This method avoids using the costly nylon bolts.
I also attached two Mr. G cells in series with the 10 plate cell. This would have lowered the cells voltage to a little over 2 volts each. But the visual gas production was very similar to what is shown in these two photos. The 10 plate cell has over 7 times the surface area- 360 sq. in. of surface area, while the Mr. G cell has 48 sq. in.

8/8/08. 10 plate cell, plates 2"x2", on right. I was wrong about the larger 10 plate cell having too much surface area. As you can see, surface area is not the problem. Single Mr. G cell on left.

8/8/08. A smack cell running in series with a Mr. G cell. This smack cell is made with 3"x6" plates-16. That makes it exactly twice the sq. in. of a wall plate style smack cell.
