Why Choose Fuel Cell Sensor Technology? - BACtrack

Fuel cell sensors rely on an electrochemical process that oxidizes the alcohol in a breath sample and produces an electrical current that the breathalyzer measures to determine the BAC.. A fuel cell consists of two platinum electrodes that are partitioned by a porous acid-electrolyte material. As exhaled air passes through the fuel cell, the platinum oxidizes any alcohol present and produces ...

An important consideration is that fuel cell oxygen sensors are used up over time. In the cell reaction above, when all available surface area of the lead (Pb) anode has been converted to lead oxide (PbO), electrochemical activity ceases, current output falls to zero, and the sensor must be rebuilt or replaced. Fuel cell sensors are designed to
