Testing Novel Nickel and Cobalt Infiltrated STN Anodes for Carbon Tolerance using In Situ Raman Spectroscopy and Electrochemical Impedance Spectroscopy in Fuel Cells
Abstract
Conventional SOFCs use Nickel Yttria‐doped Zirconia cermet anodes, whichare susceptible to degradation due to coking when operating with carboncontaining fuels. Raman spectroscopy is a powerful tool forinvestigating surface chemistry and, when combined with electrochemicalimpedance spectroscopy under <i>in situ</i> conditions, the techniquecan report the real‐time material composition of the electrode duringthe EIS measurements. Studies described in this work used <i>in situ</i>Raman spectroscopy and electrochemical impedance spectroscopy toexamine the carbon tolerance of novel ceramic anode materials comprisedof niobium doped strontium titanate infiltrated with nickel or cobaltnanoparticles. The susceptibility of these electrodes to coking weretested with CO/CO<sub>2</sub> mixtures and pure methane at 850 °C. Datashow that nickel‐infiltrated STN electrodes are still prone to cokingfrom methane. In contrast to STN electrodes infiltrated with nickel,cobalt‐infiltrated STN electrodes showed no susceptibility to carbondeposition during methane exposure within the detection limit of theRaman measurements. Neither anode showed evidence of coking from theCO/CO<sub>2</sub> mixtures. Coking correlated closely with changes inEIS measurements, with the most noticeable effects appearing in the lowfrequency part of the spectrum. <i>Ex situ</i> SEM analysis of samples before and after operation illustrates the growth of the nanoparticles.
