Abstract

A key obstacle to practical operation of protonic ceramic fuel cells (PCFCs) is the development of high efficient cathode materials. In this study, we report the identification of Gd_0.1Ce_0.9O_2-δ (GDC) infiltrated PrBaCo₂O_5+δ (PBC) - BaZr_0.1Ce_0.7Y_0.2O_3-δ (BZCY) materials as a novel triple phase (e^-/H⁺/O^2-) conducting composite cathode of PCFCs. This triple phase conducting composite cathode is confirmed to promise the extended electrochemical active sites and the accelerated oxygen reduction process. The polarization resistance (such as 0.051 Ω cm² at 700 °C under open circuit voltage) of GDC infiltrated PBC-BZCY electrode is lower than other reported PCFCs, indicating the advanced electrochemical performance. The encouraging result is definitely a significant progress for the PCFCs field, which demonstrates that desirable electrode performance can be realized by applying triple phase conducting composite electrode.
