燃料电池发电的电站应用

燃料电池作为一种高效稳定的分布式清洁能源,其发电技术在电站领域的应用备受关注,而国内燃料电池电站尚在起步阶段,因此对这一领域的研究和实践经验具有重要意义。基于韩国燃气轮机联合循环电站中燃料电池发电项目的实施,介绍了燃料电池的选型,并通过模拟运行确定了最佳余热回收方案。MCFC燃料电池额定发电效率为47%,余热回收后效率提高3.5%。这些经验将对国内未来燃料电池电站的建设起到参考和借鉴意义。

Application of Fuel Cells in Power Station

Fuel cell technology is one kind of the distributed clean energy technology with high efficiency and reliability. Its application in power generation attracts great attention from the electric power industry. As China is still in the preliminary stage in the development of the fuel cell power station, the study and experience in this field is significantly important. Based on the practice of a fuel cell power station located in a gas turbine combined cycle power plant in South Korea, this paper introduces the selection process of the fuel cell type and determining of the waste heat recovery scenario by operation simulation. The rated power generation efficiency of MCFC fuel cell is 47%, with an additional 3.5% improvement through heat recovery scenario. This experience is of guidance to potential fuel cell power projects in China.
