Résumé / Abstract

A systematic study was initiated of anode-supported solid oxide fuel cells (SOFCs) with Nd₂NiO₄ cathodes. This type of cathode, a mixed conducting K₂NiF₄-type material, can be considered as a candidate for SOFC applications. In this study, the influence of (I ) the presence of a Ce_0.8Gd_0.2O_1.9 (CGO) interlayer between the electrolyte and the cathode, (2) sintering conditions, and (3) the grain size of the powder on the performance of SOFCs with Nd₂NiO₄ cathodes was investigated in more detail. Results from current density-voltage characteristics and permeation and gas diffusion measurements showed that the electrochemical performance was promising for SOFCs including a CGO interlayer and a Nd₂NiO₄ cathode (prepared with a powder with a d₅₀ of 0.5 A/cm² or 0.8 μm) sintered at 1100°C or higher; current density at 800°C and 700 mV between 1.2 and 1.3 A/cm². The microstructure of the cathode was such that no gas diffusion problems occurred.
