Abstract
The performance of PEMFC stack can be improved significantly by optimizing the design and operating conditions. As a result, the performance of daily operation showed slight deviation (0.02-0.9%) after accumulated DSS operation for 500 hrs but the stack performance was stable. Therefore, it is confirmed that it would be improved the life-time of stack and operation reliability for the commercialization of PEMFC system.
스택의 디자인과 운전조건을 최적화하여 PEMFC stack의 성능을 상당히 증진시킬수 있다. 그러한 결과로, 500시간의 DSS(Daily Start-up & Shutdown) 누적 운전후에 일별 운전성능은 조금의 편차가 있었지만 (0.02-0.9%), 스택의 성능은 거의 변화가 없음을 알 수 있었다. 따라서 PEMFC 시스템의 상용화를 위해서는 스택의 수명 및 운전의 신뢰성을 향상시켜야 한다.
