HHO electrodes - stainless vs nickel vs platinum

[FosterVS]

I have been playing with stainless in different forms (plates, cups, etc.) with varying results. The "twister cups" while having a high output, tend to heat up so much that the metal starts to corrode, which requires disassembling and sanding the surfaces. Plus, the cups I bought predrilled had such crappy holes drilled/punched in them, I am going to garbage them.

Many documents I read about water electrolysis tend to refer often to using platinum electrodes, or nickel in some cases. I have some Monel nickel strips on order to experiment with, however finding platinum plated sheet, etc. has been a dead-end.

Anyone here experimented with these metals at all?

Platinum would probably be OK, don't know for sure but you've got to bear in mind that it's current spot price is US$1745 per ounce which is $62 per gram and that's before dealers have put their profit on top.

Another material that I've read is very good is graphite plates, it's supposed to last forever in HHO cell and give very clean results.

Good luck with it all.

The plates, etc. wouldn't have to be pure platinum, just a thin platinum coating.
I have looked at different options online for electroplating, but haven't found an easy way to electroplate platinum.

Good point about plating, I'll bet it's still pricey though. These guys say they can plate platinum onto copper:

Nice! Thanks for the link - "Platinum-plated titanium anodes used for water purification."
