LOTS more info needed!

Is this a fuel cell using Hydrogen to generate 210 mW of electric power, or a Hydrogen generator using 210 mW of electric power, or something else entirely?

Seals? Contamination? Depletion? Container material(s)? etc.

I guess it is Hydrogen Cooled Generator.

Likely leakage - and that may be very serious. Check on this aspect, may be with sensor.

You may well be right, although the OP said mw (that woud be milli-), not MW (Mega-), so I was picturing something you could lift with one hand. But since he didn't capitalize the W, he probably also missed capitalizing the M. Just a minor factor of 109...

May be scared of all the posts about caps lock . So even at the risk of misinterpretation, he left the key arms length away.
