Abstract

Current-sensing Atomic Force Microscopy (CS-AFM) and Nano-scale Impedance Spectroscopy (NIS) are key characterization tools in the research and development of diverse materials systems. 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.
