| 摘 要： | 为实现实时原位监测PEMFC的内部温度,利用光纤光栅传感技术,将光纤光栅传感器密封埋入PEMFC阴极流场板,同步在线测量不同工况条件下电池内部温度的变化。结果表明,光纤光栅传感器能实现对PEMFC的多点内温度场实时原位监测,随着电流密度阶跃的增大,PEMFC内部温度也呈现阶跃变化,且阴极大流量供气时有利于降低PEMFC内部的温度。该方法可为PEMFC内部状态参数的原位监测提供技术参考和实施方案。

| Abstract: | In this paper, the fiber bragg grating（FBG） sensing technology is employed to realize the real-time monitoring of the temperature inside fuel cell. The real-time temperature changes under different current conditions are measured by the FBG sensors sealed and embedded in the cathode flow field plate of PEMFC. Results show that the FBG sensors can obtain the real-time in-situ temperature of multiple points inside PEMFC, and with the step change of current density, the temperature also presents a step change. Besides, the temperature can be reduced when the cathode use a large amount of gas supply. The method provides a technical reference and implementation scheme for in-situ monitoring of internal state parameters of PEMFC. |
