Structure Formation in Anode and Its Effect on the Performance of Micro-Tubular SOFC: A Brief Review

Anode-supported micro-tubular solid oxide fuel cell (SOFC) offers many advantages over the electrolyte and cathode-supported confgurations in terms of simplicity, reliability, and efciency. In such design, the anode substrates should possess a highly porous structure, provide active sites reaction as well as serving good mechanical strength. This structure is desired to provide enough fuel, which in turn increases the reaction rate and reduces the concentration polarisation. Hence, pore formation in anode become a key parameter in producing high performance micro-tubular SOFC. This review is mainly focusing on the fabrication of anode substrate for micro-tubular SOFC, the types of pores in anode structure and its effect to the cell performance.
