Summary: In order to improve the contact between the electrolyte and carbon fuel in SO-DCFCs, molten metals and molten salts were used in the anode chamber. The molten medium not only allows the transportation of oxygen ions to oxidize the carbon particles, but also serves as a redox mediator to enhance the kinetics of the electrochemical oxidation of carbon. Additionally, using a liquid metal/salt anode can mitigate the negative effects of carbon contaminants on cell performance.

Summary: A molten hydroxide direct carbon fuel cell (MHDCFC) has the potential to be a clean power source in the future, directly converting chemical energy into electricity with pure CO2 product. Factors such as temperature, active specific surface area, fuel mass, and fuel type can significantly influence cell performance through polarizations. Increasing the active specific surface area may reduce activation polarization and toxic chemicals in fuel processing, but too large fuel mass or weak conductivity of fuel can weaken cell performance.

Summary: A molten hydroxide direct carbon fuel cell (MHDCFC) is a promising electricity generation technology. However, its commercialization is restricted due to intermittent fuel supply. In this study, an MHDCFC with continuous fuel supply is proposed and optimized through computational fluid dynamics (CFD) modeling. The influence of carbon type, particle size, carbon mass fraction, and temperature on the cell performance are investigated, and a membrane-less cell with activated carbon is built. The model and experiment demonstrate the feasibility of a continuous MHDCFC operating at a low temperature.

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: To enhance the fuel-to-power efficiency of molten hydroxide direct carbon fuel cells (MHDCFCs), a combined system consisting of MHDCFC, regenerator, and Stirling heat engine (SHE) is integrated. Mathematical formulas and a multi-objective function are used to evaluate the feasibility and effectiveness of the combined system. The results show that SHEs can effectively generate additional mechanical power from MHDCFC, and the proposed system has significantly higher power density, energy efficiency, and exergy efficiency compared to single MHDCFC.

Summary: A Ti-doped double perovskite oxide SFMT was developed as the anode material for coal-based DCSOFC, which showed improved catalytic activity and resistance to sulfur poisoning. Ti doping promoted electrochemical processes on the anode side and increased catalytic activity in coal gasification and CO adsorption. The operational period of the DCSOFC increased from 2 to 10 hours after Ti doping, indicating enhanced structural stability of SFMT in a sulfur-containing environment.

Summary: Using H2O2 to modify carbon black can increase the amount of functional groups on the surface, thereby increasing the metal dispersion and decreasing metal particle size. NaH2PO2 as a reducing agent can suppress the growth of metal particles. The best modified carbon black catalyst is the one modified with 30% H2O2, and the methanol oxidation activity of the catalyst is mainly related to the particle size of PtRu metal, rather than the surface area and conductivity of carbon black.

Summary: A Ce/Ti-based bimetallic metal-organic framework (MOF) showed better photocatalytic reduction of CO2 compared to an isoreticular pristine monometallic Ce-terephthalate MOF due to its highly selective CO2 adsorption capability, optimized band gaps, higher flux of photogenerated electron-hole pairs, and a lower rate of recombination. The inclusion of an amine functional group into the linker led to the reduction of Ce4+ to Ce3+, and the presence of low-lying Ti(3d) orbitals facilitated the photo-reduction reaction.
