CONNECTING MATERIAL FOR ELECTRICAL CONNECTION OF ELECTROCHEMICAL CELLS

摘要

A body suitable for conductively connecting respective electrodes of closely coupled fuel cells arranged in series circuit and operating at temperatures of at least 600 DEG C. consists of two conductively bonded ceramic materials having electronic conductivities of at least one mho/cm at 1000 DEG C. at respective ambient partial oxygen pressures between 10-5 bar and one bar, and below 10-5 bar.
