Abstract

Since the operating temperature of Solid Oxide Fuel Cell (SOFC) is high, the heat management of the gases supplied to fuel cell system is important. In this paper, the temperature characteristic of the gases supplied to the anode and the cathode of the fuel cell is studied in case of utilizing the waste heat contained in the ship exhaust gas as a heat source to heat up the fuel, gas and water supplied to a 500kW SOFC system for a ship power. For the fuel cell system proposed in this paper, the temperature of gases supplied to the anode and the cathode was the highest temperature at 963K when the exhaust gas of the fuel cell was utilized as the heat source for gases supplied to fuel cell system instead of utilizing the ship exhaust gas. In addition, the engine power did not effect on the temperature of gases supplied to the fuel cell stack.

고체산화물형 연료전지는 운전온도가 고온이기 때문에 연료전지 시스템으로 공급되는 가스의 열관리 문제가 중요하다. 본 연구에서는 선박 배기가스의 폐열을 선박 전원용 500kW급 SOFC 시스템으로 공급되는 연료, 가스 및 물을 가열하는 열원으로 활용한 경우에 연료전지 애노드 및 캐소드로 공급되는 가스의 온도특성에 관하여 검토하였다. 본 연구에서 제안한 연료전지 시스템에서는 선박의 배기가스를 활용하지 않고 연료전지에서 배출되는 배기가스만으로 연료전지 시스템으로 공급되는 가스의 가열원으로 활용한 경우의 애노드 및 캐소드로 공급되는 가스의 온도가 963K로 가장 높음을 알 수 있었다. 또한 엔진의 출력(배기가스의 유량)은 연료전지 스택으로 공급되는 가스의 온도에 큰 영향을 미치지 않음을 알 수 있었다.
