Sealed Series Cell Plate Design Project Page 1

Ok here is my Flat Plate design. The cell plates will be compression sealed.Notice the top left corner? Thats a piece of tubing installed in the gasket. The cell will be stood up on its corner the tubing pointing up.

I used Goop Plumbers Glue to attach and seal the tubing. A Thin smooth layer of glue attaches the gasket to the plate. Be sure no glue blocks or restricts the tubing.There is one tube and gasket per plate set-up this way to create individual cell packs. End plates will be one positive and the other negative. All the other plates will be neutral and have no electrical connections.

Sorry... No description for this picture at this time.

This cell stack will have 7 cells, each tube will attach to its own individual a 1 or 1 1/2 inch reservoir, made from PVC. There will be four mounted on one side and 3 mounted on the other. The tubing will enter below the fluid level in each reservoir keeping each cell filled entirely with electrolyte. The top of the reservoir will have a gas escape and will carry gas to the bubbler. Alltho with this setup you will have 7 individual refill points, there will be no possibility of current leakage. And the reservoirs will be easier to refill and maintain. (You could mount individual liquid level switches in the separate reservoirs that triggered with fluid level rise, then pump the electrolyte back into its cell via windshield washer pumps. But it would take 7 fluid level sensors and 7 washer pumps.)

Compressing the Stack with finger and blowing thru each tube to check for unrestricted gas flow. Gasket must be thick enough, so that when compression sealed, the tubes are not clamped shut.This will be 1/8 inch for this cell.
