Description

燃料电池金属双极板巡检辅助结构及燃料电池 技术领域
本发明属于燃料电池技术领域，涉及燃料电池的测试装置，具体涉及一种燃料电池金属双极板巡检辅助结构及燃料电池。
背景技术
为了保证燃料电池工作的可靠行，需要对其进行电压监测，所以必须在金属双极板上设计电压巡检辅助结构，以实现与外部导线接口连接，如图1所示，传统的做法是将外部导线接口的导线接到金属插针91上，然后将金属插针91插到金属双极板上的孔形电压巡检辅助结构92内，从而实现外部导线接口与燃料电池的金属双极板连接，能够进行电压监测。
但是，这种连接方式在大型电堆上操作困难，而且可能出现插针插歪变形、振动连接失效等故障，连接操作非常困难，无法实现集成式连接。
经过对现有技术的文献检索，发现针对燃料电池金属双极板电压检测的集成式快插装置的研究报道较少。
例如专利CN 210576577 U，其揭示的方案中采用了金属簧片替代金属插针的方式，但是缺少对金属簧片的有效固定，导致金属簧片容易在插拔过程中脱落。再次插拔时会造成对位不准而出现金属簧片变形、连接失效等故障，而且设置的导向结构仅仅是对接部位中部所有部件，极易产生对接晃动而导致连接间隙增大，以此导致振动连接失效等故障，而且容置导致金属簧片在插拔过程中脱落。
