Image of FIG. 1.
FIG. 1.

(a) Schematic illustration of the miniature environmental chamber, shown complete with various gaseous inlet/outlets, electrical feedthroughs, thermocouple, and button heater; inset: schematic illustration of the chamber while in operation, shown with tip approaching the access port to resolve electrochemical phenomena in a cross-sectional geometry. (b) Digital photograph of the chamber, under operation, as integrated with a commercial (Asylum Research MFP-3D) AFM scan head; inset: digital photograph of the chamber with the scan head removed.

Image of FIG. 2.
FIG. 2.

(a) Top view schematic illustration of the miniature chamber showing various feedthroughs, sample holder with sides of Macor (green) and copper (orange) which houses the sample (purple). (b) Schematic illustration of configuration 1, consisting of two separate copper pieces. (c) A plot of applied thermal load () versus measured sample surface temperature (). (d) Schematic illustration of configuration 2, consisting of an integrated macor-copper dovetail sample holder piece.

Image of FIG. 3.
FIG. 3.

(a) Plot of measured current versus sample temperature (degrees Celsius) for a lanthanum strontium ferrite (LSF)/scandia-stabilized zirconia (ScSZ)/LSF symmetrical fuel cell. (b) Topographic image of a ScSZ electrolyte taken under 1 V applied cathodically/anodically at 600 °C. (c)–(e) Scanning surface potential images collected of the ScSZ electrolyte from the same area scanned topographically under identical conditions. (f) and (g) Line profile analysis of the surface potential images, averaged over 10 lines between the dotted red lines in (c)–(e) for 1 V applied cathodically and anodically, respectively. (f) Inset line profile analysis for 0 V applied bias.
