Importance of Anode Microstructure in Modeling Solid Oxide Fuel Cells
A one-dimensional button-cell model is developed and applied to explore the influence of anode microstructure on solid oxide fuel cell (SOFC) performance. The model couples porous-media gas transport and elementary electrochemical kinetics within a porous Ni-YSZ cermet anode, a dense YSZ electrolyte membrane and a composite LSM-YSZ cathode. In all cases the fuel is humidified H2 and air is the ...
متن کاملEFFECT OF RHODIUM INFILTRATION ON THE MICROSTRUCTURE AND PERFORMANCE OF Ni/Ce0.8Gd0.2O2-δ CERMET ANODE FOR LOW TEMPERATURE SOLID OXIDE FUEL CELL
In order to further enhance the Ni/Ce 0.8Gd0.2O2-δ (Ni/GDC20) cermet anodic performance for low temperature solid oxide fuel cell (LT-SOFC), a study was conducted on the nanostructuring of NiO/GDC composite by only once wet-infiltration of rhodium chloride precursor. By using electrochemical impedance spectroscopy (EIS) analysis, the effect of only one drop of Rh-infiltrating solution on ...
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...
متن کاملCeramic - Based Anode for Solid - Oxide Fuel Cell Utilizes
490 MRS BULLETIN/JULY 2002 nated by intergranular fracture, while in AJM it was in a manner resembling ductile behavior. Improved surface finishing by AJM resulted in a 15% improvement in flexural strength, compared with both ground and ground-plus-lapped samples. The researchers concluded that a higher compressive residual stress observed on the AJM-processed surface, combined with the smoothe...
متن کاملEvaluation of solid oxide fuel cell anode based on active triple phase boundary length and tortuosity
An efficient procedure is presented for the evaluation of solid oxide fuel cell (SOFC) anode microstructure triple phase boundary length (TPBL). Triple phase boundary- the one that is common between three phases of the microstructure- has a great influence on the overall efficiency of SOFC because all electrochemical reactions of anode take place in its vicinity. Therefore, evaluation of TP...
