Breath analyzers (Breathalyzer is a brand name) contain an anode (negatively charged electrode) and a cathode (positively charged electrode). When you blow into a breathalyzer, the ethanol in your breath reacts with water from the air at the anode and is oxidized to form acetic acid (like in vinegar).
