Power Generation Performance of a Solid Oxide Fuel Cell Equipped With an Yttria-Stabilized Zirconia Electrolyte Formed Over a Support Metal Plate

Abstract

AbstractA solid oxide fuel cell (SOFC) formed on a stainless-steel plate having through holes was studied. The obtained metal-supported SOFC can be operated at high temperatures such as 750 °C because it comprises an yttria-stabilized zirconia electrolyte. It was confirmed that the aperture ratio of the support metal plate affected the power generation performance of the metal-supported SOFC. The power density of the obtained SOFC at 0.8 V was increased from 0.22 W/cm2 to 0.85 W/cm2 at 750 °C by increasing the aperture ratio from 0.2% to 5.3%. Thus, it was found that the SOFC formed on a support metal plate having through-holes could show a power density comparable to or higher than that of previously reported SOFCs formed on porous sintered metal supports.
