Quasi-distributed optical fiber bragg grating sensing system in the application of the measurementof the microbial fuel cell temperature field

微生物燃料电池(MFC)在近些年得到了迅猛了发展,尤其是MFC具有产电且同时处理废水的效果,引起了世界各国科学家的高度关注。如何提高MFC产电效率的问题一直是MFC的研究重点,其中温度是影响微生物活性的一个重要因素,进而影响MFC的产电效率。为了能够更好地了解温度场与MFC的产电效率的关系,本文采用准分布式光纤Bragg光栅(FBG)阵列,对MFC阳极室内温度场分布进行实时测量。实验表明:该方法能够测量MFC运行阶段阳极室内温度场分布,反应前后温度差3-4℃,该方法为研究MFC内温度与产电效率的关系提供一种新的手段。

Microbial Fuel Cells（ MFC） developed rapidly in recent years. Especially MFC makes a high attention in many nations’ scientists because of it can produce electricity and treat sewage at the same time. The efficiency of electricity production problem of MFC always been a research focus. Temperature is an important factor to affect microbial activity,then influence the efficiency of electricity production of MFC. In order to understand the relationship of temperature field and the efficiency of electricity production better,here use the quasi-distributed optical fiber bragg grating sensing system for temperature field real-time measurement in MFC anode chamber. This experiment proves the quasi-distributed optical fiber bragg grating sensing system can measure the temperature field in MFC,During the experiment temperature rise 3 degrees. provides an effective way to study of relationship between temperature and electricity production efficiency.
