Abstract

Proton batteries have brought new research directions in the field of fuel cells and energy storage. Although our R&D team has developed a prototype of the proton battery stack, there are still some problems to be solved, such as leakage and unstable power generation. In addition, simultaneously and accurately measuring multiple key physical parameters inside a proton battery stack remains challenging. The present measurement methods are external or single parameters, that has become a limiting factor. These parameters (voltage, current, temperature, flow, humidity, pressure, oxygen and hydrogen) significantly affect the performance, life and safety of the proton battery stack. To address these challenges, this study developed a micro hydrogen sensor using the Micro-electro-mechanical systems (MEMS) technology, which was integrated with the previously developed seven-in-one microsensor, the mask and layout were re-designed to increase the number of microsensors, which were combined with a Flexible Printed Circuit (FPC). Finally, the development of a flexible eight-in-one microsensor was completed, so as to improve the output and overall operating efficiency of the microsensor, and provide a reliable internal multi-parameter real-time microscopic monitoring and diagnostic tool for the development of proton battery stacks.

一种用于改进质子电池组的内部实时显微监测和诊断工具

质子电池为燃料电池和储能领域带来了新的研究方向。虽然我们的研发团队已经开发出了质子电池组的原型，但仍然存在一些问题需要解决，例如泄漏和发电不稳定。此外，同时准确测量质子电池组内部的多个关键物理参数仍然具有挑战性。目前的测量方法是外部参数或单一参数，这已成为一个限制因素。这些参数（电压、电流、温度、流量、湿度、压力、氧气和氢气）显著影响质子电池组的性能、寿命和安全性。为了解决这些挑战，本研究利用微机电系统（MEMS）技术开发了一种微型氢传感器，该传感器与先前开发的七合一微传感器集成，重新设计了掩模和布局，以增加微传感器的数量，并与柔性印刷电路（FPC）相结合。最后，完成了柔性八合一微传感器的研制，提高了微传感器的输出和整体工作效率，为质子电池组的研制提供了可靠的内部多参数实时显微监测和诊断工具。

期刊介绍： Sensors and Actuators A: Physical brings together multidisciplinary interests in one journal entirely devoted to disseminating information on all aspects of research and development of solid-state devices for transducing physical signals. Sensors and Actuators A: Physical regularly publishes original papers, letters to the Editors and from time to time invited review articles within the following device areas: • Fundamentals and Physics, such as: classification of effects, physical effects, measurement theory, modelling of sensors, measurement standards, measurement errors, units and constants, time and frequency measurement. Modeling papers should bring new modeling techniques to the field and be supported by experimental results. • Materials and their Processing, such as: piezoelectric materials, polymers, metal oxides, III-V and II-VI semiconductors, thick and thin films, optical glass fibres, amorphous, polycrystalline and monocrystalline silicon. • Optoelectronic sensors, such as: photovoltaic diodes, photoconductors, photodiodes, phototransistors, positron-sensitive photodetectors, optoisolators, photodiode arrays, charge-coupled devices, light-emitting diodes, injection lasers and liquid-crystal displays. • Mechanical sensors, such as: metallic, thin-film and semiconductor strain gauges, diffused silicon pressure sensors, silicon accelerometers, solid-state displacement transducers, piezo junction devices, piezoelectric field-effect transducers (PiFETs), tunnel-diode strain sensors, surface acoustic wave devices, silicon micromechanical switches, solid-state flow meters and electronic flow controllers.
