Research Abstract

We investigated electrode materials for protonic ceramic fuel cells. For anode materials, electroless-plating process of nickel on barium zirconate was established. But the performance was much lower than that of Pd-plated electrode. A technique for increasing surface area using acrylic beads was also investigated.In addition, water content in BaBa_<0.5>Sr_<0.5>Co_<0.8>Fe_<0.2>O_<3-d> was measured to find mix conductor of proton and hole.
