Hint: To illustrate the difference, we must focus on whether the change that occurs is reversible or not.Examples of metallic conduction include alloys, graphite and metals.
Examples of electrolytic conduction include acids, bases and salts.

Complete step by step answer:
Metallic conduction involves drifting of electrons through vacancies of conduction band in random fashion, brought about under the effect of electric field.
Electrolytic conduction is the movement of free ions in electrolyte which is either the substance in molten state or their aqueous solution.

S.No.Metallic conductionElectrolytic conduction
1.The flow of electricity takes place without decomposition of the substance.The flow of electricity takes place with decomposition of the substance.
2.There is no actual transport of matter.Transfer of matter takes place in the form of ions.
3.The conduction of electricity is due to the flow of electrons.The conduction of electricity is due to the flow of ions in the solution.
4.Metallic conductivity decreases with increase in temperature.Electrolytic conduction increases with increases in temperature.
5.Metallic conduction is a physical process that means no new substance is formed.Electrolytic conduction is both physical and chemical change.

We should remember that in fuel cells which convert chemical energy to electrical energy, protons are conducted through electrolytes while ions and electrons are conducted through electronic (metallic) conductors.
