This is my 13 plate ( -nn+nn-nn+nn-) dry cell. I used Lowes 304 stainless blank switch plates. I modified them by sawing off the ends length wise, and flattening them. I bored the holes to 5/16 diameter. I used .045 contact shelf material as gasket. On the neutral plates I cut off two corners at a 45 degree angle. On the voltage plates I only cut off one corner at 45 degrees. I then drilled the holes for the brass connecting bolt in the remaining corner. For the end caps I'm using a cheap cutting board I found at Big Lots. I have a dual bubbler set up( cheap ziploc containers) with a hydrostatic connection. I don't have it connected in this video. I'm just using the one bubbler. I am only conditioning the cell in this video. I am using 5 volts with 2 tsps of sodium hydroxide to a gallon of water. I'm using my computer power supply that I converted into a Lab power supply. Thanks for watching. Sorry about the lighting. I think that's House on the TV that you hear in the background :)
