A Guide to Electrochemical Reactions. The micro fuel cell-type electrochemical sensors do not require an external driving voltage. For example, an elec-trochemical sensor specific to oxygen has an anode, ei-ther Pb or Cd, that supplies electrons for the reduction of oxygen at the cathode. During the oxidation of the an-ode, the electrons are released which then travel via an external circuit to the cathode where oxygen molecules, concentration changes in the electrochemical cell. Remember that electrochemistry is just thermodynamics, and thermodynamics always considers relative concentrations.
