Summary: This study evaluates the performance of a hybrid supercritical carbon dioxide (SCO2) power cycle coupled with a direct carbon fuel cell (DCFC) and found that the partial cooling SCO2 is a promising option. Integrating a supercritical CO2 cycle with DCFC can compensate for efficiency and power density loss due to fuel cell temperature decrease.

Summary: A mathematical model was developed to study the gas concentration profiles across the anode of a DC-SOFC, with factors such as cathode and electrolyte design parameters taken into account. The effects of operating potential on concentration profiles were modeled, with electrolyte thickness and TPB length identified as major factors influencing DC-SOFC performance. Comparison with experimental data showed good agreement.

Summary: This study investigates the effect of surface characteristics on the electrochemical resistance of bituminous and sub-bituminous coals used in fuel cell systems. The samples were treated with acids to analyze the correlation between electrochemical resistance and chemical properties of the coal surfaces. Acid treatment resulted in enhanced power densities for both types of coals, with bituminous coal showing a more significant improvement.

Summary: In this study, a novel anode structure was designed and the performances of six coal-based fuels in MC-DCFC were investigated. The mechanisms of performance differences and the effect of operating temperature on performance were examined. The results showed that the fuel cell performance was in the following order: meagre coal (109.8) > bituminous coal (108.7) > bituminous coal char (98.1) > lignite coal (83.7) > lignite coal char (71.3) > meagre coal char (53.2) in mW cm-2. Coal performed better due to its high carbon content, high volatile content, rich oxygen-containing functional groups, larger specific surface area, stronger thermal reactivity, and other factors. The electrochemical reactivity of coal fuel increased with higher reaction temperatures and varied throughout the temperature ranges. This study suggests that using coal fuel to commercialize MC-DCFC could be a realistic alternative.

Summary: This paper presents a kinetic model for a CO gas electrochemical sensor, in which sensor behavior over time is simulated. The sensitivity and catalytic property of the sensor were found to be influenced by factors such as input pores diameter, gas passing membranes thickness, and sensor volume. Different sensors with membranes of varying porosity and thickness were made to verify the accuracy of the proposed model, showing a good match with the test results.

Summary: Mesoporous Co dendrites prepared by electroplating exhibit a high surface area and superior urea oxidation activity compared to Ni or Co nanoparticles prepared using chemical reduction. The Co dendrites show a lower onset potential and higher current output than Ni catalyst under experimental conditions, achieving a good output performance even at 20℃. These results demonstrate the potential of using nonprecious Co dendrites as anode and cathode catalysts in fuel cell applications.

Summary: This work demonstrates the first alkaline direct liquid fuel cell powered by butanediol (BD) and examines the performance and product formation differences among the four linear isomers of BD. The research shows that the 1,4-BD isomer has the highest maximum power density and potential for strong power output. Additionally, the analysis reveals the impact of the relative position of the alcohol groups on the adsorption of the molecule and the performance of the fuel cell.

Summary: The performance of an anion exchange membrane-based direct urea/O2 fuel cell (AEMDUFC) was analyzed using a mathematical model. The model was verified using experimental data and showed good accuracy. The voltage losses in the electrodes were dominant at low current density, while the voltage loss in the membrane was the highest at high current density. The structural and operating parameters of the anode side were found to be important factors for improving the performance of the AEMDUFC.

Summary: A techno-economic analysis was conducted on the production of bio-oil from catalytic pyrolysis of olive mill wastewater sludge using two different cooling schemes. The results showed that scheme-2, which utilized an absorption refrigeration machine, had slightly better process efficiency and lower production cost compared to scheme-1, which used a compression refrigeration machine. The findings support the viability of producing bio-oil on a commercial scale.

Summary: This study investigates the feasibility of using exhausted olive pomace biochar as a fuel in a direct carbon fuel cell. The results confirm the feasibility, with a maximum power density of 10 mW cm(-2) at 700 degrees C. The limited output of the fuel cell is attributed to the high ash content and low volatile matter content of the biochar.
