The influence of electron localization on the chemical expansion coefficient was examined experimentally, using a model electrode material, (La,Sr)(Ga,Ni)O3-δ. Varying the Ni content yielded differing degrees of electron localization with resultant chemical expansion coefficients evaluated by dilatometry and thermogravimetric analysis in N2/O 2 mixtures at 800 °C. In agreement with prior computational predictions, a decrease in chemical expansion coefficient was observed with electron delocalization.
