Proton-conducting fuel cells (PCFC) are clean and efficient chemical-electrical energy conversion devices, and PCFC based on BaZrO3 is promising in view point of chemically stability and high protonic conduction in the mid-temperature range. Here, we perform THz conductivity measurement of Ni and Yb doped BaZrO3, which exhibit protonic and hole conduction for improving the performance of PCFC anode.
