【 摘 要 】

This report summarizes the work done during the second quarter of the project. Effort is directed in two areas: (1) The use of a novel method to achieve a given porosity level with high contiguity and thus conductivity. (2) Relate the measured conductivity to porosity and contiguity. The rationale for these experiments was to develop cathodes with high ionic conductivity, so that the effective polarization resistance will be concomitantly lowered.
