Discolored electrode plates

[pertyfly]

So everyone...

Why is it that my plates turned a yellowy color? If you want to check, you can look at my project folder. But wherever there was soemthing touch (a bolt or washer, etc) it was normal SS color. Where there was electrolye, it turned color. Now, it is only SS304, but I was only using Lye. This shouldn't do it, as far as I know. Would amperage or lye concentrations have any affect at all?

Any ideas, I would love to know. It seemed to work fine still, but I am just curious. I don't know however, it may have affected efficiency? We'll see with further testing.

I am using 304ss and KOH in plastic containers (rubbermaid or Glad brands) and my plates and electrolyte consistantly turn brown within days with brown particulate (I assume to be rust) settling to the bottom when the cell is turned off. It does not seem to effect hydroxy production but I have not been tracking production rates over weeks. That may be something that should be tracked to see if production varies with changes in ss and electrolyte. I would hypothesise that it does.

Well, I had my electrolyte sitting in my unit for probably a couple weeks, and it didn't do anything really bad. It was just slight. So, I'm not sure if it happens with power applied, or without?
