Performance and Durability of Metal SOFCs in Alternate Fuels

Power generation from electrochemical devices based on solid oxide fuel cells (SOFCs) is in great demand for both stationary and automotive applications to achieve carbon neutrality goals by 2050. In particular, SOFCs are known for their fuel-flexible operations; for example, SOFCs can operate on simple and complex renewable fuels (such as ethanol, natural gas, jet fuel, propane, etc.). Unlike H 2 -based fuel cells, liquid and hydrocarbon fuels in SOFCs adopt the existing fuel infrastructure and contribute to reducing greenhouse gas emissions significantly. This article presents the potential of using metal-based SOFCs (metal cells) as highly performing and durable power generators. The metal cells technology could be the most accessible solution for using SOFCs for versatile industrial needs.
