Abstract

The focus of research and development on electric motorcycle range extender are system integration and energy regulation and management but the present fuel cell stack range extender still has defects, such as large volume, heavy weight and high cost. Its volume and weight will have a strong impact on the endurance of electric motorcycle. The bipolar plate takes most volume and weight of a proton exchange membrane fuel cell (PEMFC) stack and it is the key component influencing the overall power density and cost. Therefore, how to thin and lighten the bipolar plate and to enhance the performance and life of PEMFC stack is an urgent research subject to be solved for the moment and will be the key to whether the PEMFC stack range extender can be put in the electric motorcycle or not. In addition, the internal temperature, humidity, flow, voltage and current in the operation of PEMFC stack will influence its performance and life and the overall performance and life of fuel cell stack will be directly influenced by different external operating conditions. As nonuniform distribution of temperature, humidity, flow, voltage and current will occur in various regions inside the fuel cell stack, this study will use micro-electro-mechanical systems (MEMS) technology to develop a flexible five-in-one microsensor, which is embedded in the PEMFC stack range extender for real-time wireless microscopic diagnosis and the reliability test is performed, so that the actual operating condition inside the fuel cell stack range extender can be mastered instantly and correctly and the internal information is fed back instantly, the fuel cell stack range extender control system can be modified to the optimum operating parameters immediately, so as to enhance the performance and prolong the lifetime effectively.

摘要

电动摩托车增程器的研发重点在于系统集成以及能量调节与管理，但目前的燃料电池堆增程器仍存在缺陷，如体积大、重量重和成本高。其体积和重量会对电动摩托车的续航能力产生很大影响。双极板占据了质子交换膜燃料电池（PEMFC）堆的大部分体积和重量，是影响整体功率密度和成本的关键部件。因此，如何使双极板变薄、变轻并提高PEMFC堆的性能和寿命，是目前亟待解决的研究课题，也是PEMFC堆增程器能否应用于电动摩托车的关键。此外，PEMFC堆运行时内部的温度、湿度、流量、电压和电流会影响其性能和寿命，而不同的外部运行条件会直接影响燃料电池堆的整体性能和寿命。由于燃料电池堆内部各区域会出现温度、湿度、流量、电压和电流的不均匀分布，本研究将采用微机电系统（MEMS）技术开发一种柔性五合一微传感器，将其嵌入PEMFC堆增程器进行实时无线微观诊断并进行可靠性测试，以便能即时、正确地掌握燃料电池堆增程器内部的实际运行状况并即时反馈内部信息，可立即将燃料电池堆增程器控制系统修改为最佳运行参数，从而有效提高性能并延长使用寿命。
