KARPEN PILE

Any grade H2 canister will be forced by regulations.is that pure or plated silver?where did you get it?

[pomodoro]

It is silver wire for chemical experiments, but have no idea of purity. I did not buy it myself.

We can test it by dissloving a small piece in HNO3 when it comes out of that test.there must b no color change.we are getting closer to our set goal,to measure stable power outage from an gaseous overpotential difference.when we do this in the milliamp range,we make history.

I just want to point out that your cathode has only about 1cm epoxy between itself and air pomodoro.air will get in all the way through that wire bundle under the jacket.this is why I always use a single strand bare wire for contacts.I have to be cracksharp with my observation here otherwise scientist critics with sarkeizen-type characters will bash us at the first weakpoint they see (-:

I still prefer type 3, but with some pressure sensor simply because constant bubbling introduces other contaminants from the bottle. When I ran gas chromatography labs we needed oxygen traps on the uhp hydrogen because it still contained traces of oxygen and wrecked columns after months of usage.  When I dismantle this gadget 3 I will place a hose on the tap with the open end under water to check for a vacuum or positive pressure.  Another run can have the pressure regulator apply a small positive pressure throughout the run.   Regarding the treated silver, it is definitely a brown color, not grey.

I think that the small positive pressure is the way to go.
