description:
	The electrochemical performance of solid oxide fuel cell (SOFC) electrode materials is governed by the morphology and state of the "triple-point" boundaries where the electron-conducting, ion-conducting, and gas-percolating phases all meet. In the cathode, these phases are given, respectively, by lathanum sttrontium manganite (LSM), yttria-stabilize zirconia (YSZ) and the void system. We propose ASAXS studies around the Sr K-edge and, if necessary, the Y K-edge, in order to differentiate at least the void/YSZ and void/LSM interfaces. We hope also to infer infomation on the LSM/YSZ interface and to characterize the scattering morphologies.
