Abstract:Planar solid oxide fuel cells (SOFC) with CuO/gadolinium‐doped ceria (GDC) supporting anode were produced and tested in H2 and in CH4/CO2 mixture at 650 °C. The electrolyte densification at 900 °C was promoted by compressive strains induced by larger anodic thickness. The reduction behaviour of CuO/GDC anodic powders was preliminarily evaluated. The electrochemical measurements showed an increasing power density with the anode thickness (from ≈500 μm to ≈1.4 mm) reaching a maximum value of 227 mW cm−2 at 650 °… Show more
