What equipment is needed to fill an appropriate cylinder with oxygen generated by the electrolysis of water?
Update: I need someone that has experience with gas cylinders to point out potential dangers that would be present by filling this way, We've already discussed water vapor and oil potentially making its way inside. That doesn't sound good to me so I need certainty that its safe or those can be eliminated or reduced to safe levels.
Right now I would really like to know what I need so I can refill tanks myself. I'm guessing its a special adapter or replacement valve, but I don't know where to start
Would it be possible to fill an appropriate oxygen tank with the right adapters/compression system with the oxygen generated by electrolyzing water and what kind of equipment would be needed? I know for propane you can buy adapters and refill/transfer from one to another, but obviously this is completely different, and I don't know anything about oxygen valves/adapters or compression systems. Yes I know this could potentially be very dangerous and also have no interest in collecting the hydrogen.
Just to clarify we are talking about commercial grade tanks, not a 2 liter soda bottle. Also, if possible how high of purity would be expected using optimal electrodes and electrolytes to prevent corrosion and impurities. Any information at all would be very helpful.
