What's the purpose of using platinum in a cell diagram?

platinum acts as an innate (neutral) conducting metal in the galvanic cell when the chemical reaction you are observing doesn't have one.

Platinum metal is often used as an inert electrode because platinum is one of the least reactive elements. Platinum has a large ionization energy, so it can act as an "electron shuttle" without participation in redox chemistry.

You use platinum when the products and reactants of a half-reaction are in the same state (ex. aqueous).
