In cell diagrams, is it possible for platinum to only be on one side?

Yes. See the example I did in class today.

Yes it is possible because there could be a metal(solid) on one side of the galvanic cell that actually takes part in the chemical reaction that runs the galvanic cell, so it would be the electrode on that side of the cell. The other side could only have gases or aqueous solutions reacting, so they would need a metal/electrode (like platinum) that is needed to complete the circuit to transfer electrons to the other side of the cell.

I would like to add to this question. Is graphite also considered an inert conductor? Why/why not?

Yes it is, as it conducts electricity but not part of the redox reaction.
