This work was directed toward development of a scaleable fabrication methodology to produce the monolithic solid oxide fuel cell (MSOFC) and demonstration of the electrochemical performance of fabricated cells and stacks. In the fabrication effort, MSOFC cells and stacks were successfully fabricated. Material characteristics, batch formulations, and forming and processing parameters were tailored and controlled to produce the MSOFC with the desired properties, especially a close match in firing characteristics of the individual components. MSOFC stacks in sizes up to 2 x 2 x 2 1/2 in. were formed and fired to demonstrate fabrication scaleability. In the testing effort, fabricated single cells exceeded initial performance and life goals, and cell performance was significantly improved, approaching the maximum performance limited by material resistance. One-cell to three-cell stacks of up to 3-in.-square footprints were built and operated with hydrogen fuel and air oxidant.
