Conducting Metal

Is a conducting metal/solid always necessary for half reactions?

Yes, a conducting metal/solid is necessary for electrons to be transferred between half-reactions.

I think a conducting metal is required for electron transfer between two half reactions. In Dr. Lavelle's lecture on Wednesday, he stated that some half reactions have no conducting solids, so in one example platinum electrodes were used. Platinum works because it has no reaction with the solution and solely acts as a conductor for electrons to flow through.

I don't think so, some half reactions do not involve conducting metals at all. One such reaction would be the standard hydrogen electrode. Between half reactions though, a wire is needed to transfer the charges from one electrode to the other.
