Abstract
The layered perovskite structure oxide NdBaCo2O5+δ (NBCO) with rapid oxygen ion diffusion and surface exchange kinetics was synthesized by auto ignition process and initially examined as a cathode for proton-conducting fuel cells (H-SOFCs). The single cell, consisting of NdBaCo2O5+δ (NBCO)/BaZr0.1Ce0.7Y0.2O3−δ (BZCY)/NiO–BaZr0.1Ce0.7Y0.2O3−δ (BZCY) structure, was assembled and tested from 650 to 700 °C with humidified hydrogen (∼3% H2O) as the fuel and air as the oxidant. A maximum power density of 438 mW cm−2 at 700 °C was obtained for the single cell and electrochemical performance of the cell was studied.
