Abstract
A sensing device is featured that electrochemically measures methanol concentration. The sensing device has a flexible composite of layered materials wrapped about a flexible tube having aperture contact with a methanol flow stream. The layered materials sequentially wrapped on the tube are: a polytetrafluoroethylene insulation sheet; an electrically conducting mesh representing the anode current collector; a carbon-based material representing an anode diffusion medium; a catalyst-coated membrane with both sides coated by catalysts such as Pt/Ru and Pt; a carbon-based material serving as the cathode diffusion medium; and an electrically conducting mesh representing the cathode current collector.
