DEVELOPMENT OF OSAKA GAS TYPE PLANAR SOFC

摘要

Osaka Gas type planar SOFC ( OG type SOPC ) has a suitable sttucture for stacking and good thermal cycle performance. We could obtain the crack-free cells and 5-cell stack units without gas leakage by examining them before stack fabrication using non-destructive test. 1-unit generation test showed good thermal cycle performance and high power density. In the 20-cells stack generation test using 4 units, the stack performance was 404 W and terminal voltage was 13.46V at 0.25Acm~(-2) and 70% fuel utilization.
