Do you always need to include Pt in the cell diagram?

No you do not always need to include Pt in your cell diagram. Platinum is used when there are no other inert metals in the reaction in order to allow current to flow through the cell. Most the time, you see Pt(s) being used when you are dealing with a cell that has a half-reaction that does not have any solids.

Pt is only used in cell diagrams when a solid is needed to for the transfer of electrons from the anode to the cathode. If there is already a solid transferring the electrons, there is no need for Pt.

Platinum is needed when there isn't a metallic conductor. Just because there is a solid it doesn't mean it is a metallic conductor, such as I2(s).

If there is no solid metal state that works as the conducting electrode, you need a stable metal such as Pt to use.

If there is no solid metal to act as a conductor, you use platinum
