In the notation, the anode is always written on the left side, so the hydrogen electrode as the anode is placed on the left. The cathode half-reaction is on the right side. The double vertical line represents the salt bridge or porous disk that allows ion migration to maintain neutrality. Finally, the solid vertical line represents the phase boundary. Thus, the correct cell notation is: Pt(s)| H₂(g)| H⁺(aq)|| Pb⁴⁺(aq),Pb²⁺(aq)| Pt(s).
