XPS characterisation of the interface between anode and electrolyte in a proton conducting solid oxide fuel cell
Abstract
<p>In this work, we deposited by pulsed laser deposition nanometric layers of proton conducting calcium-doped lanthanum niobate (La<sub>0.995</sub>Ca <sub>0.oo5</sub>NbO<sub>4</sub>) on nickel substrates in order to fabricate model structures of the electrolyte-anode interface present in potential proton conducting solid oxide fuel cells (PC-SOFC). Characterisation by XPS of in situ reduced samples indicates the absence of chemical reaction between lanthanum niobate and nickel, confirming their reciprocal chemical stability. A peak shift to higher binding energies is observed for the elements of the electrolyte material after exposure to reducing atmosphere for several hours at a typical operating temperature for PC-SOFC. This shift is attributed to the formation of a space charge layer in the oxide at the interface with metallic nickel.</p>
