Abstract / Full Text

Electrochemical characteristics of fuel cells containing CaZr0.9Y0.1O3 – δ film supported by Ni–CaZr0.95Sc0.05O3 – δ anode are studied. It is shown that the diffusion of nickel from the electrode-support favors the increase in electronic conductivity of the electrolyte. It is found that to provide sufficiently high transport numbers of ions, the thickness of the CZY electrolyte film should not be smaller than 4 µm. The polarization losses on the anode are concluded to be the main reason for the lower power of fuel cells with thin-film electrolyte.
