Title: Cathode material for low temperature solid oxide fuel cells

The present invention relates to a solid oxide (or protonic ceramic) fuel cell, a cathode for a solid oxide (or protonic ceramic) fuel cell, and a method of making the same. More specifically, the cathode for a solid oxide (or protonic ceramic) fuel cell utilizes a phase-pure perovskite structure of the compound BaCo.sub.0.4Fe.sub.0.4Zr.sub.0.2-xY.sub.xO.sub.3-.delta., where x is between about 0 and about 0.2. The cathode material may then be utilized in a SOFT or a PCFC as either a thin film porous cathode or as nanoparticles infiltrated into a cathode bone having a different structure.
