Can someone clarify when its necessary to add an electrode (like Pt) to a cell?

You add Pt(s) as an electrode when the the half reaction does not have a solid metal for which the current can run through.

You add it to the end of the galvanic cell, so you can have solids at the end if there aren't any present. They are inert.

When there is no solid metal in a reaction, add Pt(s).
