Progress in Metal-supported Solid Oxide Fuel Cells

Abstract

Solid oxide fuel cells (SOFCs) have been attracting much attention as alternative energy conversion devices due to their high energy conversion efficiency and fuel flexibility. In current SOFCs, Ni-based Cermet anode, solid oxide electrolyte and ceramic cathode have been used. Since all components are ceramic-based materials, there is a problem in that mechanical strength and durability against thermal shock. In order to solve this problem, metal-supported solid oxide fuel cells have designed. Metal-supported solid oxide fuel cells provide significant advantages such as low materials cost, ruggedness, and tolerance to rapid thermal cycling and redox cycling. This paper review the types of metal supports used in metal-based solid oxide fuel cells and the advantages and disadvantages of each metal support.
