Jones' point about ANY exposure to H is acknowledged... That being said, does anyone know the exact procedure by which the material in the control cell was prepared and the cell assembled??? Obviously, the nichrome wire was shipped to them, but was it exposed to air (humid air will supply plenty of H)? How were the cells assembled?? I can't imagine that they were somehow assembled in a vacuum; perhaps in an inert gaseous environment??

The control cells have not been exposed to hydrogen yet. Are you suggesting that they might have been, inadvertently? Cheers, S.A.
