Sealing Plate Edges....... [:)]

[sumdude]

For those of you that actually seal the plate edges does it actually have a noticable effect on the operation of the cell?

For instance is the water temperature over a period of time reduced from before it was added?

Is production up or down?

Would it be a better alternative to use to PWM?

For instance is the water temperature over a period of time reduced from before it was added? yes, less waste heat.

Is production up or down? up

Would it be a better alternative to use to PWM? Not at all, a PWM is unrelated to building an efficient cell.


Think of a PWM as an automatic on/off switch.

thanks for the reply. I understand the operation of the pwm on and off multiple time reducing the on time in half and blah blah blah lol..

However what are you all using to seal the edges. Ive heard of marine goop, rtv sealant, tape. which one will hold up the best in the naoh or koh solution?

I have a wrapped cell which has sealed sides. I used ultra high temp black silicon to seal the sides. This is the only thing I have found that will hold up to the process. I start out running a bead on the edge of the plates as the cell is assembled. After the cell is asscembled I coat the entire side leaving the coat atleast a sixteenth thick over the entire side. This insures the silicon is all one piece of rubber. This helps to insure the seal is maintained and in place. The cell is seven plates, +nnnnn-. The spacing is maintained by nylon nuts on screws which extend through the cell. I use two liter bottles to heat shrink the entire cell when assembled. This has been a very sturdy design. The ends are open.

I used a motorcycle innertube to wrap my open bath gen with.

ok thanks for the inputs. anyone has pics they can post?

I used plexiglas to seal the edges of mine. See the link under my signature for pictures.
