Summary: In response to the growing demand for emission reduction in the marine industry, research is being conducted on efficient power conversion using sustainable fuels. Solid Oxide Fuel Cells (SOFCs) are considered a viable option for long-range shipping due to their high efficiency, low pollutant emissions, and fuel flexibility. This study evaluates the electrical and heat efficiency of a 100 kW SOFC system for marine applications fueled with methane, methanol, diesel, ammonia, or hydrogen, and investigates the use of cathode off-gas recirculation (COGR) to improve heat regeneration. The results suggest that COGR is a promising method to increase the heat efficiency of marine SOFC systems.

Summary: A novel integrated structure is proposed to simultaneously produce power and heat using biomass fuel. The integrated system consists of multiple sections including gasification, solid oxide fuel cell, gas turbine cycle, Rankine cycle, ORC, and hot air and water line. The system utilizes heat recovery to supply the required heat for gasification and air. Wood chips are used as fuel for the solid oxide fuel cell through gasification. The results show that the cycle has an output power of 152.8 MW, an electrical efficiency of 51.43%, and an overall efficiency of 81.13%.

Summary: A novel multi-generation system is proposed to recover waste heat from a solid oxide fuel cell - gas turbine system, using five different subsystems to enhance energy efficiency and exergy efficiency, with the use of waste heat for hydrogen production. Despite contributing to increased total cost rate and total exergy destruction, the subsystems also lead to improved environmental performance and payback period of the entire system.

Summary: This paper proposes a method using liquid antimony anode solid oxide fuel cells (LAA-SOFCs) as an electrochemical partial oxidation reformer of kerosene, enabling cogeneration of electricity and syngas. The study reveals that kerosene can be partially oxidized into gaseous products in liquid Sb2O3, which can be directly used to produce syngas. Furthermore, the tested LAA-SOFC using sulfur-containing kerosene as fuel demonstrated good durability.

Summary: Solid oxide fuel cell (SOFC) is an energy conversion device that can directly convert the chemical energy of carbonaceous fuels into electricity. Addressing carbon deposition in traditional nickel-based anodes is crucial for improving SOFC performance. Although alternative anode materials have shown progress, nickel-based anodes remain the most promising for commercializing SOFC due to their superior catalytic activity for carbonaceous fuels.

Summary: The La0.4K0.1Ca0.5MnO3-delta (LKCM) material was successfully prepared by partially replacing La cations with K cations in La0.5Ca0.5MnO3-delta (LCM). Doping K triggered the cathode activity of the material, and LKCM showed more oxygen vacancies and improved catalytic activity than LCM. Therefore, a proton-conducting solid oxide fuel cell (H-SOFC) using an LKCM cathode exhibited better performance than the LCM cell.
