Abstract
Abstract A Ruddlesden-Popper oxide (Pr0.9La0.1)2(Ni0.74Cu0.21Nb0.05)O4+? (PLNCN)-infiltrated BaZr0.1Ce0.7Y0.2O3-? (BZCY) is developed as an electrode for protonic ceramic fuel cells (PCFCs). {PLNCN} nanoparticles are evenly dispersed on the surface of {BZCY} skeleton by using the infiltration technology. The electrochemical behavior of the PLNCN-infiltrated {BZCY} electrodes are evaluated in terms of infiltration loading and temperature. The impedance results of symmetric cells suggest that the optimized loading of {PLNCN} is approximately 46.1 wt%. Power density of the single cell as high as 0.77 W cm?2 is achieved at 700
