The control cells have not been exposed to hydrogen yet. Are you suggesting that they might have been, inadvertently? Akira, No - I was suggesting that in previous experiments to this one - the same nichrome wire could have been used. Did they start out with a virgin wire for this experiment or not? Often experimenters cut corners and reuse items from previous runs. It is a common misunderstanding to think that all the hydrogen can be pumped out of nickel by vacuum or a combination of heat and vacuum - and the Hunt group simply may not have known how tightly the "last" proton is bound to 14 nickel atoms in a FCC crystal. The alloyed proton will not come out even at 2700 degree F. IOW you can load nickel with hydrogen up to a 1:1 ratio, but you cannot unload the last proton in the FCC crystal without melting it.
