Another plate cell design has emerged from the pond muck.
Acrylic slab sides, 61 plates 3" x 3" 24 ga 304 SS with the end plates a little taller for the only two connectors.
The plates got stacked in a fixture with 1/8" balsa wood in between each one, and the sides got treated with a combination of GOOP marine down the bulk of the center, and FUSOR brand structural sheet metal epoxy along the top and bottom. Slap on the sides and let 'er cure.
The whole thing is ~9" long, and I'm jes finishing up a containment vessel that will facilitate circulation of electrolyte, as well as provide a modicum of flash-back protection. Still gotta test it.
Driving it with 120VDC [rectified wall mains], not over 15 amps for now.
