Solid oxide fuel cells (SOFCs) represent a highly promising technology for distributed power generation and clean energy due to their superior eficiency, fuel flexibility, and low emissions. 1,2 While hydrogen is the conventional SOFC fuel, its practical implementation faces significant challenges including high production costs, storage and transportation dificulties, and leakage risks, particularly in mobile applications like vehicles and marine systems. 3,4 Owing to their high-temperature operation, SOFCs demonstrate broad fuel compatibility, enabling the use of alternative fuels such as hydrocarbons (methane, ethane, and propane), oxygenates (methanol and ethanol), and zero-carbon hydrogen carriers, including ammonia. 4,5 Among these, ammonia ofers distinct advantages as a SOFC fuel: it eliminates carbon deposition inherent to hydrocarbons,6 possesses a high hydrogen mass content (17.

What is a solid oxide fuel cell (SOFC)?
Solid oxide fuel cell (SOFC) is a third-generation fuel cell. It is a fully solid-state chemical power generation device that directly converts chemical energy stored in fuel and oxidant into electrical energy in an efficient and environmentally friendly manner at medium and high temperatures.
Are solid oxide fuel cells a viable power source?
Among various fuel cells, the solid oxide fuel cell (SOFC) has emerged as a commercially viable power source at a small scale. This paper provides an extensive review of the components, materials, design, operation, and integration strategies of SOFCs with existing thermal-based power plants.
In terms of application, most of Solid Oxide Fuel Cell is currently concentrated in small-scale energy supply systems, combined heat, power and cooling systems, etc., while research on large-scale energy storage systems, including the integration of battery isolato r, is still in the stage of verifying its feasibility.
How long do solid oxide fuel cells last?
Finally, there has been no systematic research on the life of Solid Oxide Fuel Cell, which is also a key breakthrough direction. Solid oxide fuel cells are the leaders in the future energy field. Their high efficiency, environmental protection and multi-field application characteristics undoubtedly provide us with a new energy solution.
Direct carbon solid oxide fuel cell (DC-SOFC) is a promising power generation technology using coal or other carbon-based solid materials, which can convert the chemical energy into electrical energy with high efficiency and low pollution [192, 199].
As the world pays more and more attention to clean energy and sustainable development, solid oxide fuel cells (Solid Oxide Fuel Cells), as an efficient and environmentally friendly energy conversion technology, are gradually becoming a shining star in the future energy field.
