need help with an electrolasis machine, hydrogen gas gen

[BigBang J]

hey guys, I have been looking into making electrolasis devices for producing hydrogen gas for various projects such as: Hybrid gun fuel, torches, etc.

I have been looking around for some intermediate to advanced information on the subject and mostly all I can find is beginner stuff.
I have just found out that there can be parallel or series plates and that series is mor efficient. Anyway I would like to know all I can about the subject cause I want to build one that will last a long time and not have to be changing out the electrodes/plates every other day.

So if anyone can tell me what is the best materials to use and such I would be grateful.

Thanks in advance.

It's not electrolysis, but it's relevant if you only want hydrogen. Linky.
