Reports Outline Electrochemicals Research from D. Grondin and Colleagues
November 11th, 2011
According to the authors of a study from Karlsruhe, Germany, "Classical solid oxide fuel cell anode (Ni-cermet) could be employed as solid oxide electrolysis cell cathode. Ni-cermet has been synthesized and tested as solid oxide electrolyzer cathode using three-electrode techniques between 70 degrees C and 900 degrees C. yttria stabilized zirconia was used as the electrolyte and Pt as the counter electrode."
"Polarization curves and impedance spectra have been analyzed for two gas compositions. The presented results demonstrated an influence of Ni-cermet electrode behavior upon gas composition and temperature. The present results highlight a mechanism changing on Ni-cermet...
