Summary: Coal-fueled direct carbon solid oxide fuel cell (DC-SOFC) is an attractive device, but coal ash can be toxic to SOFC components. Pyrolyzing anthracite at 600 degrees C to obtain semi-coking coal improves cell performance due to higher carbon and catalyst content. Both coals were compared as DC-SOFC fuel and the semi-coking coal showed higher power density and longer discharge time, indicating better stability.

Summary: A porous ceramic support designed as a multi-functional independent catalyst layer improves stability of solid oxide fuel cells running on liquid hydrocarbon fuel and offers additional in-situ catalyst regeneration capability. The independent catalyst layer can be simply assembled on top of the anode, avoiding the mismatch of thermal expansion coefficients and enhancing stability. A current collector layer can also be inserted to improve current collection efficiency and electrochemical performance.

Summary: This research demonstrates that high H atom utilization can be achieved by matching the rates of NH3 decomposition and H-2 electrochemical oxidation; as temperature decreases, the rate of H-2 oxidation decreases more rapidly, suggesting lowering NH3 flow velocity to optimize H atom utilization; under specific operating conditions, tubular DA-SOFC fueled with NH3 shows potential for high-efficiency power generation.

Summary: The study found that in a solid oxide fuel cell-gas turbine hybrid system, higher fuel utilization factors and pressure ratios increase the air flow requirement to maintain acceptable temperature differences and thermal gradients. The highest efficiency is achieved at higher operating voltage, moderate pressure ratio, and moderate fuel utilization, while the lowest cost of electricity is obtained at lower operating voltage, the same pressure ratio, and lower fuel utilization.
