    The copper vessel itself acts as the positive electrode. A porous pot containing diluted sulfuric acid is placed in the copper vessel. An amalgamated zinc rod dipping inside the sulfuric acid acts as the negative electrode. When the circuit is completed, diluted sulfuric acid in the porous pot reacts with zinc so as to liberate hydrogen gas.

  • John Frederic Daniell () Corrosion

    The amalgamated zinc rod (anode) had a binding screw. The top of the copper cylinder contained the other binding screw (cathode). Daniell's last work on a gravity type of battery was later to become one of the most popular in the 1850's. He fused two electrolytes; copper sulfate (CuSO 4) and zinc sulfate (ZnSO 4). A copper electrode was placed ...
