Abstract
Electrochemical techniques which can be used in SOFCs are limited due to the high operating temperature (600–1000 °C) and solid-state nature of the electrode and electrolytes. Thus it is important to have a proper design and cell configuration to ensure the accuracy of the polarization performance measurement of SOFCs. This Chapter will start with the test station design and electrode arrangement. The inrinsic realtionship between the position of the reference electrodes, equipotential line and polarization evaluation of electrode and electrolyte reactions will be discussed. The most common electrochemical techniques used in SOFCs such as electrochemical impedance spectroscopy and galvanostatic current interruption will be introduced.
