[en] Screen-printing is used to prepare thick films of stabilized zirconia and doped ceria, with different shapes of electrodes. This technique gives an electrode area to electrolyte thickness ratio from 1 to 2 orders of magnitude higher compared to that of conventional pellets. The paper gives some details on the preparation methods, and preliminary results on electrode polarization measurements on yttria-stabilized zirconia and gadolinia-doped ceria at temperatures as low as 620 K. Below 750 K and 50 Hz, the impedance of the cells is entirely due to the metal/oxide/gas interface, hence this method could lead to a better understanding of the electrode processes and catalysis mechanisms.
