Proton-conducting membranes have great potential for applications in proton conducting membrane reactors forthe production of commodity chemicals or synthetic fuels as well as for use in solid oxide fuel cells. However, toensure the long-term structural stability under operation relevant conditions, the mechanical properties of themembrane materials need to be characterized. BaCe0.65Zr0.2Y0.15O3-δ is of particular interest due to its provenfunctional properties. In this research work, the mechanical properties of BaCe0.65Zr0.2Y0.15O3-δ were determinedon different length scales using different methods including impulse excitation, indentation testing, and micropillarsplitting. A detailed microstructural analysis of pillars revealed that irregular results are caused by porescausing crack deflection and complex crack patterns. |
