Abstract

We have fabricated methanol sensor for monitoring the methanol concentration in direct methanol fuel cells. A thin composite nafion membrane was used as an electrolyte. We have analyzed the I-V characteristic of the fabricated methanol sensor as functions of methanol concentration, catalyst electrode and platinum (Pt) thickness. When we measured the sensor with 10 nm Pt and at 1 V, the current value was 1.30×10^-6, 1.96×10^-6, and 2.80×10^-6 A for three methanol concentration of 1, 2, and 3 M, respectively. And when the methanol concentration was fixed at 2 M, the current value of the fabricated device with Pt of 5, 10 and 15 nm was 3.06×10^-6, 1.96×10^-6, and 1.00×10^-6 A, respectively.
