- Abstract
- Solid oxide fuel cells that incorporate stabilized-zirconia electrolytes commonly use the transition-metal oxide perovskite La0.875Sr0.125MnO3+delta as the cathode. While in operation, the cathode can be subjected to significant stresses, because of thermal expansion mismatch between mating components. The mechanical behavior of La0.875Sr0.125MnO3+delta has been studied using three-point bend strength measurements at ambient, 400 degrees C, 800 degrees C and 1000 degrees C. The results show that phase transformations have an important role in the mechanical-strength behavior. The results also indicate some unique strengthening effects that are associated with the evolution of the unit cell with temperature and the increasing symmetry of the crystal lattice.
