Abstract
The anode supported planar SOFC concept, with a 15 pm thin YSZ electrolyte layer has shown excellent performance operating on hydrogen and air at temperatures of 800 °C (0.26 W/cm2) without any noticeable degradation in the first 500 h. These low operating temperatures in combination with the higher value for the thermal expansion coefficient of the anode substrate allow the use of commercially available ferritic steel as metallic interconnect. A new design for the gas manifolding using metallic components was introduced in order to facilitate the assembly process and to reduce the cost of stack manufacturing. Test results from among others a 10-cell stack of 10×10 cm2 cells operating on hydrogen and air and a 2-cell stack operating on methane are presented.Keywords
