Solid oxide fuel cells (SOFC) have long held the promise for carbon free/carbon neutral power generation. After decades pursuing innovative system and stack geometries a consensus has emerged around atmospheric pressure, anode-supported planar SOFC with metallic interconnects, produced through tape casting, screen printing and thermal spray deposition. This design suffers from high operating temperatures, metal parts (high temperature stability), extremely precise geometric tolerancing, and inherent compromises in performance and durability necessary to address material incompatibilities. To combat these issues a redesign of the SOFC materials is needed. Therefore, in this work, we manufactured a new anode and cathode zirconia based ceramic and tested their resistivity from room temperature to 1000C. In addition, voltage-current curves were collected using hydrogen gas and air at atmospheric pressures between 400 to 1000C on a co-sintered button cell.
