Abstract :
If an online and real-time measurement system is realized using a shear horizontal surface acoustic wave (SH-SAW), the SH-SAW sensor can be used in many fields. As detection principle of the SH-SAW is relative measurement, the SH-SAW sensor needs reference liquid. When the SH-SAW sensor is installed into a flow tube, it is difficult to measure reference liquid. In this paper, we discuss methanol concentration measurement method of a direct methanol fuel cell using the SH-SAW sensor.
