Aravind, P.V. (author), Ouweltjes, J.P. (author), Woudstra, N. (author), Rietveld, G. (author)The impact of biomass-derived contaminants on solid-oxide fuel cells (SOFCs) with Ni/gadolinia-doped ceria (GDC) anodes was investigated using electrochemical impedance analysis. Measurements were carried out with symmetric test cells under a single-gas atmosphere. The impact of H2S, HCl, and naphthalene in the gas stream on the performance of...journal article 2007

Aravind, P.V. (author), Ouweltjes, J.P. (author), Schoonman, J. (author)Electrochemical impedance measurements were carried out on symmetrical nickel/gadolinia-doped ceria test cells. For H2, N2, and H2O mixtures, the diffusion length obtained based on the impedance measurements is on the order of centimeters. This high value of the diffusion length is attributed to the flow field in the reactor. It is suggested...journal article 2009

(author)This paper presents a three-dimensional model of an anode-supported planar SOFC with corrugated bipolar plates serving as gas channels and current collector above the active area of the cell, based on the direct internal reforming reaction of methane and the electrochemical reaction of hydrogen. A co-flow system with gas mixture of methane,...journal article 2009

(author)This paper presents the influence of operation conditions including steam levels, current density and operating time on the performance of Solid Oxide Fuel Cells (SOFCs) fuelled by tar- containing biosyngas. The performance of SOFCs was evaluated by means of recording impedance spectra and polarization curves of the cells before and after tar...journal article 2011

(author)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...journal article 2013

(author)Mathematical modeling tools are useful for predicting the safe operation limits and efficiencies of SOFCs. For a particular SOFC design, variations in internal methane reforming kinetic parameters is expected to affect local gas compositions, local Nernst voltages, current densities and temperature profiles and in turn the safe operation limits...journal article 2013

Patel, H.C. (author), Biradar, N. (author), Venkataraman, V. (author), Aravind, P.V. (author)Ceria and nickel pattern anodes are prepared and tested in order to gain a fundamental insight into the electrochemical oxidation of hydrogen on either of these surfaces. It is found that ceria is highly active towards electrochemical oxidation of hydrogen with lower polarisation resistance because of the mixed ionic electronic conductivity of...journal article 2014
