报告摘要：A new bifunctional fuel-cell/battery hybrid system has recently been proposed and developed in the presenter’s group. The new system is comprised of a reversible SOFC as the electrical charger/discharger and a redox-active metal/metal-oxide chemical bed as the energy store. During operation, the oxygen-electrode of the system is constantly open to air, performing reduction (discharge) and evolution (charge) reaction of oxygen molecules, while the fuel-electrode enclosing a Fe/FeO_x redox couple as the chemical bed and a mixture of H₂/H₂O as the oxygen shuttling gas performs the energy storage functionality via reaction Fe+xH₂O=FeO_x+xH₂. The dual functionality of the system is a distinguished feature compared with other metal-air batteries: power generation when the fuel-electrode chamber is open to a flowing fuel, and energy storage when the fuel-electrode chamber is closed. The presentation highlights pros and cons of the new battery chemistry and recent progress made in the presenter’s lab in performance enhancement through materials advancement and microstructural optimization.
