- Status #13 Cell 4A3
-
- Yesterday's event to ponder may have an explanation after all. It now looks
- like there is a gas leak. If we assume that the cathode puffed out some D2
- gas, and it blew the cell seal, then the event would be explained. I.e. the
- loss of gas would explain the accumulation of "cold".
-
- Last night in the course of normal checks I found the cell leaking. Now the
- question is why. Unfortunately this cell has a teflon to glass seal. Not too
- easy to do right. I think the next design will have only a teflon face in the
- cell and the rest will be made of something that can be glued.
-
- My preference at the moment is epoxy fiberglass. Does anyone know if this
- is likely to be a bad material?
-
- It is likely that there was a real pressure surge in the cell. My pressure
- switch tries to hold very near ambient pressure, but there is a time lag as it
- can only adjust about 6 cc a minute.
-
- The seal was tested at an atmosphere or so. To get beyond that would have
- required the sudden appearance of 50 cc+ of gas. That is a lot to come out of
- the 0.1 cc cathode in a hurry. The electrolysis makes 10 cc a minute of
- combined D2 and O2, so it should take a while to build up pressure even in the
- unlikely case of loss of catalyst function everywhere at the same time. We
- have seen such events, but usually the catalyst starts working again in a few
- minutes. Sigh! More things to do to make the experiment better!
