Investigation the performance of solid oxide fuel cells and the role of nanotechnology in its construction

Nanotechnology is well used in the development and performance improvement of solid oxide fuel cells (SOFCs). The high operating temperature of SOFCs (700-900 ° C) has led to serious shortcomings in their overall performance and durability. Hence, the high operating temperature has been reduced to the average temperature range of approximately 44-700 Celsius, which has improved performance and subsequently commercialized SOFCs as portable energy sources. However, at reduced temperatures, challenges arise such as increasing the internal strength of fuel cell components. Although this may not be as serious as the problems that arise at high temperatures, it still significantly affects SOFC performance. This paper deals with the work of researchers in the field of application of nanotechnology in the construction of SOFC through different methods. These methods have successfully eliminated or minimized internal resistance and shown significant improvements in SOFC energy density at reduced temperatures.
