When there is no metal present to conduct the flow of electrons from anode to cathode that is when we use an inert electrode like platinum.

Platinum is used in a cell diagram as an electrode when no other solids are present, it is added to either end of a cell diagram depending on where its needed

Platinum is an inert electrode. It is used when theres is no metal present.

Mercury(l) is one non-solid that is an electrode so when it is used in a re-dox reaction, you don't need to use Platinum. (Ignore this part if you don't understand).

Since platinum is inert, it will not interfere with the overall redox reaction. Therefore it can be used in the place of a solid metal, transferring electrons from an aqueous solution to the cathode.

Can add Pt (s), or C (graphite)... Can also use Hg (l) if your ions / solids involve mercury.
