Abstract

<p>To install huge renewable energy such as solar, wind power, energy storage and transportation system should be installed since renewable energy has vulnerability with time fluctuation. In such systems, toluene-methylcyclohexane (MCH) conversion system are considered as a good candidate of it. Toluene would be hydrogenated into MCH then hydrogen would be transported and stalled as MCH. They are paid highly attention since they can be handled liquid at ambient temperature and pressure. But a problem to cause reduction of total efficiency is the transported water from anode side at cathode. In the toluene-MCH conversion cell, toluene is hydrogenated at cathode side and water electrolysis is performed at anode to produce proton.</p>
