These have been used in fuel cell research to distinguish between various sources of cell losses; for example, ohmic losses in the electrodes and electrolytes, activation over-potentials due to reaction kinetics, and mass transport effects. Proton transport and water diffusion phenomena are locally observed to determine the ionic channel structure and mechanism. © The Electrochemical Society.
