Nickel/doped-ceria composites are promising electrocatalysts for solid-oxide fuel and electrolysis cells. Very often steam is present in the feedstock of the cells, frequently mixed with other gases, such as hydrogen or CO2 . An increase in the steam concentration in the feed mixture is considered accountable for the electrode oxidation and the deactivation of the device. However, direct experi...
The effect of the surface state on electrochemical performance nickel gadolinium-doped ceria (NiGDC) cermet electrodes in direct CO2 electrolysis was studied by operando near ambient pressure X-ray photoelectron spectroscopy combined with on-line gas phase and electrical measurements. limited at overpotentials below carbon deposition threshold to avoid irreversible cathode deactivation. results...
