HHO electrodes - stainless vs nickel vs platinum

It would be better to use distilled water. Tap water contains minerals, flouride, chlorine, and many other bad things to place in these cells.
At least by using distilled water, even if you need to add something to it, you know exactly what is in it. And susequently what youll be getting out of it isnt poisonous.

Remember what goes into our cells is as important as what comes out.

True.

I've actually used deionized water. But for now, I just use tap water and use distilled water later. Have you built and tested generators as per your research?

I tried DC source but encountered some problems and discovered its limit. Are you an electrochemist? I discovered something in my tests that there might be stray currents I produced in the process. You mentioned also about corrosion and I want to know more on current exchange density.

I am not an electro-chemist. Studying metals, and corrosion has been my job for the last two decades. I have been working on these cells for almost 3 years now. I am currently studying mechanical engineering. Being I am in class, I am able to pick the brains of my professors. A lot of my subject matter works right around what I've been working on. So this helps explain a lot of things, and has sent me in new directions with my design. Better to research first, than waste money building, then changing my mind after Ive bought tons of material some of which is very expensive.
I have picked the brains of many electro-chemists, metallurgists, and engineers. At every point I have been warned to completely stay away from stainless steel. So I do.

Id love to help you on the current density problem your having. But Id have to look it up, which would make me playing catch up to you. lol
The corrosion cell is at the heart of what we are doing in these cells. Only we are forcing it to happen under applied voltage.
Give a call to your local college, and ask a professor. Many are willing to help, some even get excited about your project as well.

I have built wet cell versions for testing purposes. I have two more combinations to test before I build my separator full flow cell.

Also in response to an earlier post. After i called and chewed the ear off of the engineers at a non-nuclear hydrogen production company. They told me over I believe it was 8 volts hydrogen production quality starts to suffer. So they run their massive electrolyzers on only 8 volts. Now this may have been per plate gap, or over the whole thing. I dont remember.
