Structure of BaZrxCe0.8-xY0.1Yb0.1O3-delta (0 <= x <= 0.8) proton conductors at room temperature and fuel cell operating temperature.
Proton conductors based on Ba(Zr,Ce)O3-delta perovskites have been proposed as electrolytes and electrodes for proton-conducting solid oxide cells (PC-SOCs), i.e., fuel cells (PC-SOFCs) and electrolysers (PC-SOECs). Co-doping of barium zirconate-cerate with Y and Yb has been shown to improve ionic conductivity, catalytic activity for hydrocarbon reforming and stability for high Zr content. The structure of Yb-based compounds (called BZCYYb) has not been carefully studied in the literature. This proposal aims to fill this gap by studying the structure of five BZCYYb compositions (three intermediate and two terminal compositions) at room temperature and fuel cell operating temperature. Neutron diffraction is the only diffraction technique capable of detecting slight distortion of the oxygen lattice and providing the effective structure.
