LBNL-55226 Catalyst-Infiltrated Supporting Cathode for Thin-film SOFCs

Abstract

Abstract The fabrication and electrochemical performance of co-fired, LSM-SYSZ [i.e. to 53 % improved peak power densities by as much as 1.3, shifting the diffusion limitation to high current densities. Cobalt infiltration into the support improved those by as much as a factor of 2 due to a significant reduction in non-ohmic resistance. These results demonstrate that cobalt catalyst-infiltrated LSM can be effective and low-cost supporting electrodes for reduced temperature, thin film SOFCs
