Description

一种模块化电堆电压巡检采集装置及燃料电池 技术领域：
本发明涉及一种模块化电堆电压巡检采集装置及燃料电池。
背景技术：
燃料电池是一种通过电化学反应将燃料(氢气)和氧化剂(空气/氧气等)的化学能转化为电能的装置。单节燃料电池或者简称单节电池，由两个双极板和单个膜电极组成，工作电压在0.4V—1.0V范围内，无法满足实际工作的要求。实际应用的燃料电池堆一般是由上百片双极板和膜电极经过层叠式装配而成，膜电极在两片双极板之间构成一个单节电池，上百片的单节电池相连构成整个电堆。
燃料电池电堆中的每片单节电池的性能是影响燃料电池电堆性能的重要因素，燃料电池正常运行时每片单节电池电压应该保持一致性。如果局部一片单节电池的流道内液态水堵塞、燃料/氧化剂短缺和制造/组装一致性差等原因造成局部单节电池电压严重低于整体的平均电压，必须及时停止燃料电池的运行以保护燃料电池电堆本身，所以电池电堆各片的单节电池电压的准确监测是保证电堆安全可靠运行的重要措施。
电池巡检系统(CVM)是一种用于实时监测电堆单节电池电压的装置。电池巡检系统由电压巡检采集端子结构和电压测量电路系统组成。电压巡检采集端子结构对于电压测量电路系统与电池电堆各单节电池的有效连接起着关键的作用，保证采集的电压信号的准确性和稳定性。
目前常用的电压巡检采集端子系统使用金属端子焊接(金属双极板)或胶接(石墨双极板)到双极板、铜制的探针插入双极板卡槽内等。这些电压巡检采集端子系统存在长期工作后接触端松弛而接触不良、无法吸收电堆组装误差而导致安装困难、双极板胶接端子导致破坏电堆破损、维修和更换操作复杂等问题。
为解决该技术问题，目前已有一种电压巡检采集端子，具体可参考专利号 为：CN202021215609.8,专利名称为：一种燃料电池电堆单电池电压巡检采集端子，本实用新型包括固定支架、探针集成件和PCB插接件，多个探针集成件间隔设置在固定支架上，且探针集成件通过导线与PCB插接件连接，所述探针集成件包括探针基座和探针，所述探针基座固定在固定支架上，且探针基座上设置多个贯穿孔，所述探针设置在贯穿孔内，所述探针包括探针套和插设在探针套内的探针头，且探针套和探针头之间还设有弹簧，可以在不修改电堆结构的基础上，无损、高效、稳定安装于电堆电压探测区，稳定输出电压探测信号，通过变更探针型号可以适用于预留探测槽或未预留探测槽的石墨双极板电堆、金属双极板电堆。但是该专利的燃料电池电堆单电池电压巡检采集端子存在以下问题：
1)只能适配单节电池的数量是固定片数、固定间距的一款电堆，兼容性差，如果需要采集多款不同规格的电堆的各片单节电池电压就需要开发多款电压巡检采集装置，无形中增加了开发测试成本和延长研发周期；
2)端子间距固定，要求所有端子同时插在对应位置并接触良好有困难，对于装配一致性不高的电堆，无法正确使插针接触到位。如果双极板间的塑料膜挡住了顶针，顶针调整位置起来非常困难。
发明内容：
本发明的目的是提供一种模块化电堆电压巡检采集装置及燃料电池，解决现有技术中只能适配单节电池的数量是固定片数、固定间距的一款电堆，兼容性差，无形中增加了开发测试成本和延长研发周期的技术问题。

实施例二：
如图1、图13至图16所示，一种燃料电池，包括电堆7和电堆电压巡检采集装置，电堆7由若干片单节电池堆叠而成，其特征在于：电堆电压巡检采集装置采用实施例一所述的一种模块化电堆电压巡检采集装置，利用电压巡检采集单元3的顶针31顶在单节电池的电极上采集各单节电池的电压。
工作原理：根据要测试的电堆中单节电池的数量安装对应数量的电压巡检采集单元3在滑轨2上，随后将两块固定块1分别安装在滑轨两侧并与电堆固定牢靠。此时电压巡检采集单元3并未一一对应到电堆的双极板。调节最左边电压巡检采集单元3，通过拉住导线36将顶针31与电堆拉开距离，此时用工具在滑轨2的调节窗口23将电压巡检采集单元3调整到电堆最左边双极板处，随后松开导线36，顶针31的针头311在弹簧37的作用下顶到最左单节电池的边双极板上，并紧密接触，然后拧紧紧钉螺钉34，紧钉螺钉34螺钉头接触滑轨2的滑轨导向凸台21侧壁，从而锁定电压巡检采集单元3，此时最左侧的电压巡检采集单元3安装完成。方法同上，依次安装固定剩余所有的电压巡检采集单元3，保证每一块电压巡检采集单元3的顶针31的针头311对应一片单节电池的双极板且接触良好。每一个电压巡检采集单元3对应电堆的每一片单节电池进行电压采集然后送到电压巡检装置6，电压巡检装置6通过信号转换模块将采集到的每一片单节电池的电压信号传输到计算机终端，通过计算机终端监控电堆中各单节电池的电压信号是否准确和稳定，保证采集的电压信号的准确性和稳定性。
