摘要

为了深入研究燃料电池内部传热传质之间的关系

以自制的薄膜传感器为测量单元

实现了燃料电池内部温度和热通量的同步在线测量。实验结果表明自制的薄膜传感器可以测量膜电极表面的瞬态变化

且传感器对电池性能的影响较小;同步测量的数据显示

放电过程中温度的动态响应要迟于热流的动态响应

由于膜电极热导率的变化以及甲醇窜流的影响

相对于温度的阶跃变化

热通量呈现持续变化的趋势。

Abstract

In order to study the relationship between heat transfer and mass transport in fuel cell

a micro thin film heat flux sensor

which can simultaneously measure the temperature and heat flux inside the fuel cell

has been designed and fabricated.The results show that the self-made sensor can detect the transient temperature and heat flux on the surface of membrane electrode assembly(MEA)and the sensor is slightly affect the performance of fuel cell.The simultaneous measurement indicates that the dynamic response of temperature is slower than that of heat flux during the fuel cell discharge process.The heat flux appears to be constantly changing with respect to temperature because of the variation of heat conductivity coefficient of MEA and the effect of methanol crossover.
