Researchers are addressing the challenge of transporting gaseous hydrogen safely and at a large scale by exploring the use of liquid methylcyclohexane (MCH) as a carrier. To achieve this, a team at the University of Tsukuba has developed a high-entropy alloy anode for organic hydride electrolytic synthesis. The process involves transferring toluene from a cathode to the new anode under highly acidic conditions. The study identified that benzoic acid, an oxidized form of toluene, plays a significant role in polymerization and anode degradation. By preventing toluene oxidation, the risk of benzoic acid formation is mitigated, enhancing anode durability. Compared to conventional iridium oxide anodes, the high-entropy alloy anode demonstrated superior durability and cost-effectiveness. The study's findings mark a significant step towards establishing a more sustainable and efficient hydrogen transportation infrastructure, crucial for the future of clean energy.
