Abstract
An electrochemical fuel cell measures ethanol in human breath and a process maintains such an electrochemical fuel cell. The electrochemical fuel cell includes a first electrode (), a second electrode () and a third electrode (). The first electrode () is used as a measuring electrode in a regular operating mode of the electrochemical fuel cell and as a measuring electrode or as a reference electrode in a maintenance mode of the electrochemical fuel cell. The second electrode () is used as a counter electrode in the regular operating mode of the electrochemical fuel cell and as a measuring electrode or as a reference electrode in the maintenance mode of the electrochemical fuel cell. The third electrode () is used as a counter electrode in the maintenance mode of the electrochemical fuel cell.
