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.

Mars Gasket is Astronomical Success!

Mars Gasket is a Sky High Achievment!

Consistant efficiency of 5.7 to 5.97.

This is the future of dry cell technology.

The Mars Gasket

The Campbell Gasket was tested. The 40-mil PVC shower pan liner proved to be too flexible and I am in the process of reconstructing the cell with new Campbell Gaskets made of acrylic.

Today I found that Mars1952 on YouTube has been building a cell with a similar concept. I’ve included a picture of what I perceive his design to be - with some of my own embellishments. The gasket design that Mars1952 has come up with is called the Mars Gasket

I want to build a cell with the Mars Gasket to see how well it performs. I believe his design is superior to mine, in that it is much easier to construct. It is thinner and less expensive. If both work equally well; which I believe they will. I will have to concede and let the Campbell Gasket fade into infamy as a valiant attempt to control current leakage.

Stainless Steel Power Terminal Posts

When I bought bolts to make my first wet cell I bought all stainless steel. That makes a lot of sense to me because those bolts (even the terminal posts) were going to be in the electrolyte.

Today while experimenting with the computer power supplies I happened to touch one of the terminal posts to the cell. It was HOT! I mean it burned my finger. Right away I start thinking it had a bad connection. Nope the connection was good. Then I put an ohm meter from the top of the bolt to the bottom and found 0.2 Ohms.

At 15 amps that 0.2 ohms was robbing my system of 45 watts and causing my cell to have less voltage than it could and should have.

It turns out that stainless steel is not a very good conductor of current. I hate to think about this, but many of my experiments over the past two months have had voltage reading taken at the terminal where this voltage drop would have been over looked. My data has been compromised and I will now have to do many of my tests over after replacing the bolts with ordinary steel. The good news is that my mmw will probably improve when I install the new bolts.

Here's a link to my YouTube video showing th heat lost at a bolt.
