A Methanol Sensor Operated in a Driven Mode

Abstract
A sensor outputs a signal related to the concentration of a methanol in an aqueous solution. The sensor includes a membrane electrode assembly (MEA) having a cathode side and an anode side. A cathode current collector suports the cathode side of the MEA and has a flow channel therethrough for flowing a stream of the methanol solution and opening therethrough for providing access of the methanol solution to the cathode side of the MEA. An anode current collector supports the anode side of the MEA and is sealed to the MEA to exclude air from the anode side of the MEA. A voltage source is connected to the MEA for electro-oxidation of methanol permeating across MEA from the aqueous methanol solution to produce an output current that is functionally related to the concentration of methanol in the aqueous solution without interference of air on the methanol oxidation electrode.
