I know that I will have sparks and small flames as with the open system so now I would like to know if there is significant danger of explosion. Is anyone aware of reports of a relatively low volume open to the air glass cell exploding and causing injury or damage to the surroundings? Most of the jar volume will likely be filled with a mix of hydrogen and oxygen plus room air. I have not calculated the amount of energy contained within the captured hydrogen since a bad calculation could be dangerous. Please give me guidance before I reconnect this beast as it now is on standby.
This paper looks at various combinations

H2-Air -- lower explosion limit is 4.3 mole% H2
H2-O -- lower explosion limit is 4 mole% H2
Can you put in a baffle or something to keep the H and O separate?
Maybe a U-tube would be better than a jar.
