Stainless cathode might be ok while being plated, because the negative
potential will stop oxidation.
I've heard platinum anodes are no good either in chloride, they slowly
corrode. Anyway, like I said earlier, people normally use metal oxide
coated anodes for chlorine oxidation. You should be able to buy small
metal oxide coated titanium anodes. In Melbourne, Australia I know of a
place that makes you these anodes. I remember reading an article on the
web on how to make your own lead(II) oxide anodes on a titanium substrate.
yea, this is it I think:
