A proton battery is a hybrid battery produced by combining a hydrogen fuel cell and a battery system in an attempt to obtain the advantages of both systems. As the battery life of a single proton battery is not good, the proton battery stack is developed by connecting in parallel, which can greatly improve the battery life of proton batteries. In order to obtain important information about the proton battery stack in real time, a flexible six-in-one microsensor is embedded in the proton battery stack. This study has successfully developed a health diagnostic tool for a proton battery stack using micro-electro-mechanical systems (MEMS) technology. This study also focused on the innovatively developed hydrogen microsensor, and integrated the voltage, current, temperature, humidity, and flow microsensors, as previously developed by our laboratory, to complete the flexible six-in-one microsensor. Six important internal physical parameters were simultaneously measured during the entire operation of the proton battery stack. It also established a complete database and monitor system in real time to detect the internal health status of the proton cell stack and observe if there were problems, such as water accumulation, aging, or failure, in order to understand the changes and effects of the various physical quantities of long-term operation. The study found that the proton batteries exhibited significant differences in the hydrogen absorb rates and hydrogen release rates. The ceramic circuit board used in the original sensor is replaced by a flexible board to improve problems such as peeling and breaking.
质子电池是一种通过将氢燃料电池和电池系统结合而生产的混合电池，旨在获得这两种系统的优点。由于单个质子电池的电池寿命不佳，因此通过并联连接来开发质子电池组，这可以大大提高质子电池的电池寿命。为了实时获取有关质子电池组的重要信息，在质子电池组中嵌入了一个灵活的六合一微传感器。本研究利用微机电系统（MEMS）技术成功开发了一种用于质子电池组的健康诊断工具。本研究还专注于创新开发的氢微传感器，并将我们实验室先前开发的电压、电流、温度、湿度和流量微传感器集成在一起，以完成灵活的六合一微传感器。在质子电池组的整个运行过程中同时测量六个重要的内部物理参数。它还实时建立了一个完整的数据库和监测系统，以检测质子电池组的内部健康状况，并观察是否存在诸如积水、老化或故障等问题，以便了解长期运行中各种物理量的变化和影响。研究发现，质子电池在氢吸收率和氢释放率方面表现出显著差异。将原始传感器中使用的陶瓷电路板替换为柔性板，以改善诸如剥离和断裂等问题。
