  2. Daniell cell - Wikipedia

    en.wikipedia.org/wiki/Daniell_cell

    The porous pot cell consists of a central zinc anode dipped into a porous earthenware pot containing a zinc sulfate solution. The porous pot is, in turn, immersed in a solution of copper sulfate contained in a copper can, [clarification needed] which acts as the cell's cathode. The use of a porous barrier allows ions to pass through but keeps ...
