Preparation of NiO-YSZ/YSZ bi-layers for solid oxide fuel cells by electrophoretic deposition
A simple and cost-effective method, starting with electrophoretic deposition (EPD) on a carbon sheet, has been developed for preparation of a iO-YSZ anode and thin, gas-tight YSZ electrolyte layer on it for use in solid oxide fuel cells (SOFCs). The innovative feature of this approach nables the deposition of anode materials as well as the YSZ electrolyte, which were subsequently co-fired in ai...
متن کاملElectrophoretic deposition of MnCr2O4 coating for solid oxide fuel cell metallic interconnects
In the present study, Mn - Cr spinel powder was synthesized through a solid state reaction. In the next step, the electrophoretic deposition (EPD) method was used to apply the MnCr2O4 spinel, as an oxidation-resistant layer, on SUS 430 stainless steel in a potential of 300 V/cm. The coated and uncoated samples were then pre-sintered in air at 900 °C for 3 h followed by cyclic oxidation at 800 °...
متن کاملA new approach to microstructure optimization of solid oxide fuel cell electrodes
Designing optimal microstructures for solid oxide fuel cell (SOFC) electrodes is complicated due to the multitude of electro-chemo-physical phenomena taking place simultaneously that directly affect working conditions of a SOFC electrode and its performance. In this study, a new design paradigm is presented to obtain a balance between electrochemical sites in the form of triple phase boundary (...
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...
