The sweet spot

It appears that 2.15v is the sweet spot. At least for the 0N1 cell I tested today with a precision power supply that Greg loaned to me.
All the test were done at about 13.3 degrees C. No corrections were made for temperature. It only needed to be relevant to itself since it was all the same temperature.
The exposed surface of each plate is 4" x 10" with a 40 mil gap.

Not included was a test at 9v and 108 amps. It was more for fun than anything else. The efficiency dropped to about 1.5 mmw and I almost lost my battery cables doing that. It produced over 1.5LPM! Keep in mind it's just two plates. The temperature jumped up to 79 degrees C. According to D3's Faraday calculations I hit 128%. I'll admit it was a bit frantic and my measurements are probably of a bit.

I built this 0N1 cell to see if a single cell (at the sweet spot voltage) would work better than a cell with neutrals. Turns out they are both about the same. I had planned to build a true series cell with 6 individual cells in series. But I believe I've confirmed that the neutrals do just as good a job. I had always had my doubts because if you look at a wet cell most of the bubbles seem to come from the end plates.

Update to the License Plate Generator.

The gaskets have not worked out. The design is basically OK. 5.9 mmw was satisfying, but the gasket material is a problem. I'm going to try ceramics next. I found a source for dielectric ceramic paste. It is made to be fired onto 304 stainless, but 100ml costs $250.00. I'll try a prototype with ordinary pottery glaze before investing that much money. The problem is adhesion to the steel and the difference in coefficient of expansion

One other problem I've had is my passages are too small for a design that has all it's plumbing on one side. The rear plates become starved for fluids and literally fry the KOH to a biscuit. I have new plate design that will allow each plate gap to be supplied with it's own 1/4" plumbing. This will be a true series cell.

My idea is to make a tab at the top of each cell so that I can screw a fitting into the plate. There will be six tabs and six 1/4" connections so each cell is completely separate from the next. Basically I will build six separate cells and stack them together. They will share a plate between them so that the voltage is divided. I want to do this because I think it will work more efficiently than neutral plates, and there will be only one hole in each cell. This will get a ceramic collar and I plan to put a patch of ceramic directly across from the hole to make certain there is no current leakage.

If this one does not work out I think I will have run out of ideas.
