Spray coating of dense proton-conducting BaCe0.7Zr0.1Y0.2O3 electrolyte for low temperature solid oxide fuel cells
In this work, we report the spray coating, a simple and effective method, to prepare proton conducting BaCe0.7Zr0.1Y0.2O3 (BCZY) membranes on the pre-annealed porous anode substrates. The effects of sintering temperature on the electrolyte membrane and anode microstructure, proton conductivities of...
