We have an application that requires hydrogen with a flow of circa 800ml/minute.
Previously we have relied on cylinders of hydrogen but we are now thinking of using a hydrogen generator.
I think my maths is correct in that a large cylinder of hydrogen (7.2 cubic metres) if the whole thing leaked into the room which has a volume of circa 110 cubic metres this would give a % of hydrogen in the room of 6.5% which is above the explosion threshold of 4% ( LEL). If we switched dot a hydrogen generator at 800mls/min even if we left that running to atmosphere for 24 hours we would only manage to reach 1% volume in the room.
So unless anyone can see anything wrong with my logic a hydrogen generator is a very good idea?
I wonder if anyone is using a generator and what make etc. I see them available from China for around £2000
