摘要
高温固体氧化物电池(solid oxide cell,SOC)储能技术,将电能转换为氢能进行存储。所得氢气一方面可以转换回电能,另一方面还可以通过加注天然气管道或应用于交通、化工行业等方式拓宽氢能的应用领域,实现超大容量储能,从而为水电、风电等可再生能源发电富余电能的消纳提供一种大规模的储能方式。目前,SOC储能技术研究尚处于起步阶段,该文首先提出了一种通用型SOC储能测试平台设计方案,既适用于电解水制氢的电解电池(solid oxide electrolysis cell,SOEC)运行模式,又适用于发电供热的燃料电池(solid oxide fuel cell,SOFC)运行模式。其次,设计了平台分别运行于SOFC、SOEC时的主要测试流程。最后,基于一个100 W电堆的测试结果,验证了平台设计方案及测试流程的可行性,同时验证了SOC储能技术的高效性。
High temperature solid oxide cell（ SOC） storages electricity through electrolysis of water into hydrogen. The hydrogen produced could be converted back to electricity,and also could be injected into gas pipeline or applied into traffic or chemical industry,which could greatly broaden the application of hydrogen,realize super-large capacity energy storage and provide an ideal option for huge amount storage of curtailed water or wind power. Currently,the research of SOC for energy storage is still in its infancy. This paper firstly proposes a general design plan for SOC test platform,which could be applied to the operation mode of both solid oxide electrolysis cell（ SOEC） that can electrolyze water into hydrogen and solid oxide fuel cell（ SOFC） that can cogenerate heat and power from hydrogen; and then,presents the main test process of the platform for operation on SOFC and SOEC separately. Finally,the feasibility of the design plan and test process of the test platform as well as the high efficiency characteristic of SOC energy storage technology are verified based on the experiment data of 100 W SOC.
