One of the major drawbacks of carbon-fueled battery cells is the intrinsic presence of CO2, which impedes CO oxidation and, therefore, lowers the energy density of the cell. In the journal Angewandte Chemie, researchers at Nanjing Tech University and Curtin University in Perth describe a novel dual-phase ion-conducting ceramic membrane that is absolutely gas-tight but highly permeable for CO2. Integrated in a solid-oxide fuel cell (SOFC) with solid carbon as an energy carrier, it enables efficient removal of CO2 resulting in enhanced power density of the electrochemical cell.
