I'd rather use Pd and Sb salts and a carbon electrode; it's hard enough to control the relative composition without an anode adding more of one kind of metal. Besides, I just want to measure the voltage/current curve for the Sb/HCl system and the mass change of the cathode; with that info we can make an informed guess on the input energy. Doing good calorimetry would take someone parting with some coin, but I'll do the VI curves for the antimony rod. K.
