It is filled e.g. with diluted aq. $\ce{KCl}$,* and plugged by diaphragms to hinder the travel of $\ce{K+}$ / $\ce{Cl-}$ into either one half cell across this boundary. You do not want a travel of matter (e.g., $\ce{Cu^{2+}}$) across this connection into the other half-cell. <br/> * An example of a strong electrolyte (i.e., complete dissociation) of ions with similar mobility which are not subject to electrochemical reaction in the difference of electrode potentials of your intended half-cell reaction(s). | |
