We have a PGSTAT-302 potentiostat/galvanostat with a FRA-2 model (frequency response analyser) to characterise MEAs or fuel cells in general using complex impedance spectroscopy techniques. By using this equipment, we can implement nearly all the techniques based on electrochemical analysis, linear or cyclical voltammetry or the complex impedance spectroscopy we have already mentioned. This equipment is, therefore, highly useful for studying batteries, fuel cells, supercondensers, corrosion measurements in material, coatings, etc.
