SOFCと溶融炭酸塩を用いたハイブリッドダイレクトカーボン燃料電池の発電特性

抄録

Highly efficient energy conversion systems for converting solid fuels such as coal and biomass to electricity are required for clean energy production. Direct carbon fuel cells (DCFCs) directly convert the chemical energy in the solid char into electricity without the need for a gasification process. In this study, a hybrid DCFC using SOFC and molten carbonate was developed. As a result, a stable discharge was achieved when a level of carbon/carbonate slurry was low. Meanwhile, the continuous discharge was not achieved when the level of slurry was high. This was because carbon particles were biased toward the surface due to the buoyance, leading to less contact between the anode and the carbon.
