Fuel Cell Characterization

In terms of maximized electronic and minimized ionic conductivity a material is desirable which is—in the entire partial pressure range occurring in fuel cells—characterized by regime I or II (Fig. 3.2.7). LaCrOs doped with several percent of for example, Sr, Mg or Ca, however, lies in the transition region between regimes III and IV [179-181] and hence exhibits an oxygen partial pressure dependent electronic conductivity (Fig. 3.2.11).

Solid Oxide Fuel Cell. A fuel cell characterized as having a solid oxide electrolyte that separates the air electrode (cathode) from the fuel electrode (anode). 

Since a fuel cell is an electrochemical device, electrochemical mefliods are deemed to play important roles in characterizing and evaluating the cell and its components such as the electrode, the membrane, and the catalyst. The most popular eleetroehemical characterization methods include potential step, potential sweep, potential cycling, rotating disk electrode, rotating ring-disk eleetrode, and impedance spectroscopy. Some techniques derived from these methods are also used for fuel cell characterization.
