If you call your experiment "cobalt platinum", you state that cobalt produces electrons and platinum absorbs them. No ! Platinum has no chemical effect. In the cobalt hydrogen cell, the anode is made of Cobalt metal that loses electrons according to : $\ce{Co -> Co^{2+} + 2 e-}$ and on the platinum electrode, the ions $\ce{H+}$ are reduced according to : $\ce{2H^+ + 2 e^- -> H2}$ So some new $\ce{H2}$ bubbles will appear on the platinum sponge. | |
