Aravind, P.V. Faculty Mechanical, Maritime and Materials Engineering Department Process and Energy Date 2013-10-01 Abstract Pattern anodes can be used to localize reactions and study individual processes like charge transfer, adsorption, diffusion etc. Ceria and Nickel (Ni) pattern anodes were fabricated with the same dimensions with Triple phase boundary (TPB) lengths of 0.2707 m/cm2. Electrochemical Impedance Spectroscopy (EIS) of Ni anodes yielded results comparable with the results in literature (0.0001 Scm-2 at pH2O = 2.4 kPa and 700oC). Ceria shows a different value for conductivity compared to the nickel, possibly because of the mixed electronic ionic conductivity of ceria and the spreading of the TPB over the surface of ceria. Identifying rate limiting mechanisms on ceria pattern anodes and comparing them with those of nickel gives a more complete picture about elementary processes at the cermet anode.
