Titainium plates? Check this out.

well I thought nickel was apt to corrode as well that why I suggested silver plating
I plated a few things in a bucket over night and it worked extreamily well
and my thoughts were to put a raft of copper plates in a bucket all wired to the negative side
and a silver fork or spoon or something on the positive side and let them COOK for a few days on a low amp trickle charger or medium amp charger at 3 or 4 amps max.... increasing the electrolyte to achieve the amp draw desired... and then just let them go for a few days to a week and get a good coating of silver on the copper plates....
...
My own experiments consisted of normal steel and silver utincles.... and the normal steel tubing took the silver very well... in fact I made 4 tubes inside of tubes cells that should work well if I ever try them out....I did finish up one of them and tried it out but the amp draw was very low even with max electrolyte being used... because the spacing of the tubes being used was rather wide...about 1/4" apart....
still the IDEA has potential .... if you can find some close fitting tubes and plate them with silver it may indeed be as good as stainless steel as far as corrosion resistance is concerned...
Personally I was thinking of trying it with copper tubing because of the low resistance of copper
then coat them very well for a week or 2 and see how long the coating lasts !
.... it may well make a superior cell because of the lower resistance of the copper and have increased output because of it.... but as of right now its just a guess.....

Bob, I think you you should go out and build a dozen generators with titanium plates.

  Titanium metal is very reactive with Oxygen; in fact it will burn in air or in oxidizers such as are used in pyrotechnics.

It is also able to readily absorb hydrogen to form a hydride.

What will  happen is that the Positive plate will become oxidized on the surface by the first rush of current flow. After that it will be coated with an insulating layer of Titanium Dioxide which will prevent further current flow thus reducing production.

The fix is to use another metal for the Positive plate, such as stainless.

hg2,
That makes you wonder about the claims at the start of this thread.
I queried our lab rats and they said that as they only dissolve titanium in Aqua Regis,  they didn't know what effect Caustic Soda etc will have. But I have obtained two very carefully weighed samples (to within .001 gramme) that I intend to leave in two different strength NaOH solutions for a week before re-weighing them again.  Also a couple of bits to make a two-plate cell.  So we'll see what happens.

Sounds like a good experiment,I'm anxious to see the results.Are you going to try KOH as well to see if there're any different effects?

Btw the data I posted was from a very HHO knowledgeable source,leaving me to believe it may very well be true.

Have you guys considered using Platinum coated Titinium plates like they use in water ionizers? If interested check this out:
