Solid Oxides

Solid oxide fuel cells (SOFCs), which are still the topic of a strong research movement, offer great promise. In contrast with most additional types of fuel cells, SOFCs are solid state devices, requiring high operating temperature (800–1000°C). In this chapter, we will focus on describing the operating principles of SOFCs, their construction (electrolyte anode, cathode, and interconnect), and the main problems currently limiting their commercial success. Moreover, the laws of thermodynamics are the academic basis for several kinds of electrochemical galvanic cell. They are employed to explicate electrochemical and mechanical components of SOFCs. Furthermore, the boundaries and advantages of SOFCs related to energy, the situation, and maintainable progress are reviewed and limited prospective uses, by way of lasting impending movements for supportable advance, and the forthcoming of such strategies are argued in this chapter.
