Review—The Thermistor-Electrode as a Temperature Sensor to Obtain Thermodynamic Data of Electrochemical Systems

The measurement of the interfacial temperature variation associated with the electrochemical Peltier heat has been carried out by employing a variety of temperature sensors. Among them, the use of a high-precision thermistor inserted in the working electrode is a sensitive arrangement with satisfactory precision to measure the temperature variation given by the electrochemical reaction. The use of this arrangement is demonstrated in several works that combine thermometric measurements with routine ac/dc electrochemical measurements. This document briefly compiles relevant previous publications illustrating the application of the electrode-thermistor in electrochemistry as a feasible arrangement to obtain highly relevant thermodynamic data, such as the entropy changes and the molar electrochemical Peltier heat. A brief discussion concerning the challenges and approaches for the future is also included.
