Molten Metals and Molten Carbonates in Solid Oxide Direct Carbon Fuel Cell Anode Chamber: Liquid Metal Anode and Hybrid Direct Carbon Fuel Cells

To enhance the contact between electrolyte (source of O2−) and carbon fuel in solid oxide–direct cells (SO-DCFCs), molten metals salts were used anode chamber. Oxygen ions can dissolve be transported medium to three-phase boundary reach oxidize particles. improve sluggish kinetics electrochemical oxidation carbon, same media act as redox mediators. Moreover, using a liquid metal/salt anode, tolerant impurities, negative effect contaminants on cell performance is mitigated. In this work, an overview SO-DCFCs with metals, carbonates, mixed metals/liquid carbonates chamber presented their was compared that conventional SO-DCFCs.
