Radial cell production pattern (pics)

[Jaxom]

Most of you know that I put together a cell with a slightly unorthodox design. The electrodes are not parallel to each other, instead they radiate out from the center of the cell like spokes on a wheel. This has led to some curiosity about the production distribution of the cell, mainly whether the electrodes produce at the center more than the outer edges. I finally got the cell (well, half of it anyway,) into a clear container so I could see the actual production and get pics of how it was distributed. I was surprised by what I found.

The only container I could easily come up with was a two-liter soda bottle with the top cut off of it. It only had the capacity to hold the bottom half of my cell, so during these tests I cut the current flow down to a little over half what I've been running. These shots are taken at 12.5V and 10-12A.

This is a shot of the cell approx. 2 seconds after startup.



This is a closeup of the cell from a low angle, it shows how the production is surprisingly even all the way to the outer edges of the electrode plates.



This is a shot after about 30 seconds of run-time. I just threw it in for illustration.

I also found that the camera I'm using is capable of 3-shot bursts, so I took a startup progression to show that the production is even all the way across the plates, even on intial startup. Thanks again Dave for hosting these for me.

Awesome, love the container too!!! This is all too much fun for me. I haven't spent the time to model your design, but I think I will and send you the pdf files on it so you got it. I also have an idea for your plates I'll model up for you.

Have you gotten to check what kind of output it is doing yet? Looks real cool design. But cool won't cut it if it does little production. But I do give you an A+ for the design. Looks almost like a airplane engine or something.
