“…In addition, some enterprises explored the feasibility of utilizing simulated CBM and have achieved remarkable results . In fact, several foreign companies, including NexTech Materials, Mitsubishi Heavy Industries, Osaka Gas, BlueGen Household Generator, and Bloom Energy, already have mature methane-fueled SOFC systems. − Although domestic methane-fueled SOFC systems have not yet been applied on a large scale, these systems have also entered the trial operation stage. For instance, a 20 kW class carbon-based SOFC system from Jincheng Coal Mining Group has been successfully tested in 2020…”

With the growing global demand for clean energy, more and more attention has been given to the energy conversion efficiency of low-quality fuels. A solid oxide fuel cell (SOFC) is expected to be one of the ideal technologies for clean and efficient utilization of low-concentration coalbed methane (CBM) because it can achieve efficient utilization of low-quality fuels. This review examines the challenges of SOFC technology fueled by low-concentration CBM. In comparison to fuels such as hydrogen and natural gas, lowconcentration CBM usually contains a large number of other gas components in addition to methane, which reduces the chemical reactivity of CBM and leads to a decrease in the utilization efficiency. The effects of different carbon-containing fuels on the cell performance of SOFC have been investigated by a great deal of research, and the results reveal that methane tends to be the main source of carbon deposition, whereas oxygen-containing fuels can have a positive effect on carbon deposition. In the current SOFC technology fueled by hydrocarbon fuels, concentration polarization is also a major factor contributing to the lack of durability and stability of the cell, with the exception of carbon deposition and sulfur poisoning. In addition, the temperature and other operating environments also have different degrees of influence on the cell performance in the SOFC technology fueled by low-concentration CBM. Therefore, the development of cell materials and the optimization of the system structure of a low-concentration CBM-fueled SOFC are still key research directions for the future.

“…In addition, sub-MW-level SOFC stacks can operate at optimal fuel efficiencies, making them ideal for use in distributed power generation applications as compared with conventional gas turbines which require GW-level operations to reach optimum efficiencies [2,[11][12][13]. Furthermore, the reverse operation of SOFCs as solid oxide electrolysis cells (SOECs) is a versatile method for energy storage and is critical to complement power grids with high proportions of renewable energy such as wind or solar.…”

Solid oxide fuel cells (SOFCs) represent next-generation energy sources with high energy conversion efficiencies, low pollutant emissions, good flexibility with a wide variety of fuels, and excellent modularity suitable for distributed power generation. As an electrochemical energy conversion device, the SOFC's performance and reliability depend sensitively on the catalytic activity and stability of electrode materials. To date, however, the development of electrode materials and microstructures is still based largely on trial-and-error methods because of the inadequate understanding of electrode process mechanisms. Therefore, the identification of key descriptors/properties for electrode materials or functional heterogeneous interfaces, especially under in situ/operando conditions, may provide guidance for the design of optimal electrode materials and microstructures. Here, Raman spectroscopy is ideally suited for the probing and mapping of chemical species present on electrode surfaces under operating conditions. And to boost the sensitivity toward electrode surface species, the surfaceenhanced Raman spectroscopy (SERS) technique can be employed, in which thermally robust SERS probes (e.g., Ag@ SiO 2 core-shell nanoparticles) are designed to make in situ/operando analysis possible. This review summarizes recent progresses in the investigation of SOFC electrode materials through Raman spectroscopic techniques, including topics of early stage carbon deposition (coking), coking-resistant anode modification, sulfur poisoning, and cathode degradation. In addition, future perspectives for utilizing the in situ/operando SERS for investigations of other electrochemical surfaces and interfaces are also discussed.

Electric Power Development Co., Ltd. (JPOWER) started Tubular Type SOFC module development in collaboration with Mitsubishi Heavy Industries, Ltd. (MHI) in 1991. Since 2001 proof of concept of module structure, which was designed through the various trial and error, has been verified using the 5kW class cartridge and the 25kW class Sub module composed of 4 cartridges. The concept of module structure was verified with more than 1,400hrs operation using the 5kW class cartridge in 2003, followed by more than 500hrs operation of the 25kW class Sub module in 2006. Then the verification demonstration of the 150kW class atmospheric SOFC CHP system using accomplished module structure was planned. The prototype system was installed in 2006 and commissioning and operation test were started at the beginning of 2007. In this paper, the prototype atmospheric SOFC CHP system development and its operation test result are introduced.
