| Outline of Final Research Achievements |
In this study, I focused on carbon deposition phenomena in biomass fueled solid oxide fuel cells (SOFCs). The carbon deposition at the SOFC anode degrades the electrode performance. Although the deposition is prevented to keep the performance conventionally, it was aimed that the deposition became controllable using a carbon separation method due to the system improvement. At first, in-operando visualization of the deposition was achieved to quantify the amount of deposited carbon. Then the performance of electrode materials with carbon deposition durability was evaluated. A pre-treatment reactor to separate the carbon was proposed to prevent the excess carbon deposition at the anode. Furthermore, a CO2 emission factor of proposed system was quantified using system process analysis. According to the emission factor calculated in this study, the contribution in carbon-minus was quantified at the carbon neutral biomass fueled SOFC system.
