Active Cathodes for Super-High Power Density Solid Oxide Fuel Cells through Space Charge Effects. Quarterly Technical Report, January 1, 2004 through March 31, 2004

摘要

This report summarizes the work done during the sixth quarter of the project. Effort was directed in three areas: (1) Further development of the model on the role of connectivity on ionic conductivity of porous bodies, including the role of grain boundaries and space charge region. (2) Calculation of the effect of space charge and morphology of porous bodies on the effective charge transfer resistance of porous composite cathodes. (3) The investigation of the three electrode system for the measurement of cathodic polarization using amperometric sensors.
