    Then I mean an commercial operating device. What I can se from here at least 3 MA is needed. That goes through the metal electrodes which must get awful hot. They are quite small and bigger ones just requires more current, doesn’t it. It must run in hours each time and at least several hundreds hours before replacement. Less running times will be to expensive and difficult to maintenance. Also hydrogen often makes metals get swollen.

    Well I wonder is it possible to use metal electrodes in the long run. Can they ever take the impact of the extreme current. If not this construction can’t work commercially, otherwise it’s still promising. Anyone who now how stressed the electrodes are and if my assumption of needed current is reasonable.
