A promising direct carbon fuel cell based on the cathode-supported tubular solid oxide fuel cell technology

Abstract A novel direct carbon fuel cell is designed and fabricated using cathode-supported tubular solid oxide fuel cell technology, which makes the research and optimization of fuel electrode much easier. The maximum power density of a SO-DCFC (solid oxide direct carbon fuel cell) single cell is 172.7 and 91.1 mW cm −2 at 900 and 850 °C, respectively, with carbon as the fuel humidified nitrogen to initiate reforming reactions. Results show that the cathode supported tubular design may have future promise.
