چکیده
In the present study, solid oxide cells (SOCs) were operated in electricity generation (solid fuel cell, SOFC) mode and hydrogen production electrolysis SOEC) mode. The electrodes fabricated with nickel-gadolinia doped ceria (Ni-GDC) nickel-yttria stabilized zirconia (Ni-YSZ) composites investigated. correlations between changes microstructure degradation of electrochemical performance are discussed. mechanisms correlated Ni phase found to be similar for Ni-GDC Ni-YSZ electrodes. On other hand, stability ceramic differs significantly two electrode materials.

Importance of oxygen spillover for fuel oxidation on Ni/YSZ anodes in solid oxide fuel cells.
Using first principles simulations and the Monte Carlo method, the optimal structure of the triple-phase boundaries (TPB) of the Ni/Yttria-Stabilized Zirconia (YSZ) anode in solid oxide fuel cells (SOFCs) is determined. Based on the new TPB microstructures we reveal different reaction pathways for H2 and CO oxidation. In contrast to what was believed in previous theoretical studies, we find tha...
متن کاملThree-dimensional analysis of solid oxide fuel cell Ni-YSZ anode interconnectivity.
A method is described for quantitatively analyzing the level of interconnectivity of solid-oxide fuel cell electrode phases. The method was applied to the three-dimensional microstructure of a Ni-Y2O3-stabilized ZrO2 (Ni-YSZ) anode active layer measured by focused ion beam scanning electron microscopy. Each individual contiguous network of Ni, YSZ, and porosity was identified and labeled accord...
متن کاملOperation of Ni-YSZ Anode Supported Solid Oxide Fuel Cell on Different Simulated Syngases
Ni-YSZ anode supported solid oxide fuel cells (ASCs) were tested under various simulated syngas. There was no voltage degradation of the cell operated on 41%H2-7%CH4-6%CO-11%CO2-35%H2O fuel condition for nearly 450 hours. However, the high vapor content reduced the open circuit voltage (OCV) and discharge voltage. The cells run steadily with most dry syngas until the simulated reforming tempera...
متن کاملThe mechanical and electrical properties of Ni/YSZ anode support for solid oxide fuel cells
The most commonly used solid oxide fuel cell (SOFC) anode material is a two phase nickel and yttria stabilized zirconia (Ni/YSZ) cermet. And the mechanical stability of anode support layer, in anode-supported electrolyte designs, is very important for large scale applications. During the assembly of stack and normal operation, the cermet anode should withstand enough mechanical loading to preve...

Following exposure to ppm-level hydrogen sulfide at elevated temperatures, a section of a solid oxide fuel cell (SOFC) Ni-YSZ anode was examined using a combination of synchrotron-based x-ray nanotomography and x-ray fluorescence techniques. While fluorescence measurements provided elemental identification and coarse spatial mapping, x-ray nanotomography was used to map the detailed 3-D spatial...
