AB - Abstract: This report presents some of the key laboratory electrochemical battery testing methods that are used in fuel cell research. Methods such as voltammetry, chronoamperometry, chronopotentiometry, and electrochemical impedance spectroscopy are of major importance. All the electrochemical corrosion tests are performed through a tri-electrode polarization cell setup containing a reference electrode, a counter electrode, and the working electrode (metal sample of interest) in an electrolyte solution. All three electrodes are connected to a potentiostat. Corrosion of metal occurs through an oxidation-reduction (redox) reaction. All the above testing methods can be performed by manipulating the current and voltage responses from the cell. Potentiostatic experiments (voltammetry and chronoamperometry) are performed using constant potential at the working electrode and recording the current response while galvanostatic experiments (chronopotentiometry) and vice versa. The measured data through all these experiments can provide very useful information regarding reaction reversibility, diffusion coefficient, reduction potential, rate of chemical reaction, durability, adsorption, voltage losses, and effective resistance to the mass and charge transport offered by electrode material.
