Abstract:
The design of metal-supported solid oxide fuel cells (MS-SOFCs) has again aroused interest
in recent years due to their low cost of materials, strength, and resistance to thermal cycling, as
well as the advantages of manufacturability. MS-SOFCs are promising electrochemical devices for
hydrogen energy. Compared to SOFCs, where ceramic electrodes or electrolytes are used as a carrier
base, they are of great interest due to their fast start-up capability, greater reliability, mechanical
stability, and resistance to the thermal cycle. MS-SOFCs have many advantages over conventional
ceramic-based SOFCs, with the selection of metal-based electrode materials (anode, cathode) and
their degradation processes being some of the biggest challenges facing researchers. Therefore, this
review reports on the state of the latest research on MS-SOFCs with various structures, discusses the
corresponding electrode materials and their existing problems, and puts forward topical issues that
need to be addressed in MS-SOFCs.
