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...

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...
