Ex-situ experimental benchmarking of solid oxide fuel cell metal interconnects

Solid oxide fuel cells (SOFCs) can convert hydrocarbon fuels, such as methane, into heat and electricity with a high conversion efficiency. The fuel flexibility of the SOFC derives from the high operating temperature (600-900 °C). Such a high temperature s ...
