Abstract

This paper describes a thin film thermal sensor developed for real-time measurement of temperature in an operating polymer electrolyte fuel cell (PEFC). The sensor stack is less than 10 μ thick and is realized using micro-fabrication techniques. Experimental results show that the sensor is around 68 Ω and has a linear response of 0.206 ± 0.006 Ω/°C in the 20-100°C temperature range and is robust enough to withstand the electrolyte expansion forces that occur during the water uptake. Moreover, thermal simulation results show that the sensor has no significant effect on the local temperature distribution.
