Abstract

Temperature, voltage and fuel flow distribution all contribute considerably to fuel cell performance. Conventional methods cannot accurately determine parameter changes inside a fuel cell. This investigation developed flexible and multi-functional micro sensors on a 40 μm-thick stainless steel foil substrate by using micro-electro-mechanical systems (MEMS) and embedded them in a proton exchange membrane fuel cell (PEMFC) to measure the temperature, voltage and flow. Users can monitor and control in situ the temperature, voltage and fuel flow distribution in the cell. Thereby, both fuel cell performance and lifetime can be increased.

摘要

温度、电压和燃料流量分布都对燃料电池性能有很大影响。传统方法无法准确确定燃料电池内部的参数变化。本研究通过微机电系统（MEMS）在 40μm 厚的不锈钢箔基底上开发了灵活多功能的微传感器，并将其嵌入质子交换膜燃料电池（PEMFC）中，以测量温度、电压和流量。用户可以原位监测和控制电池中的温度、电压和燃料流量分布。从而提高燃料电池的性能和寿命。
