Solid oxide fuel cells that are designed in different geometrical structures (planar, tubular, flat-tubular, etc.) dirt-free, quiet, and efficient run using fuels including contagions fuels. In this work, the performance of a 3D model direct ammonia feed anode supported flat-tubular solid cell having six supply channels was developed, investigated, elucidated numerically comparison with hydroge...

in the present study, the effect of porosity on the cathode microstructure (50:50 wt. % lsm: ysz) of a solid oxide fuel cell (sofc) has been examined. a 3-d finite element method for mixed ionic and electronic conducting cathodes (miec) is presented to study the effects of porosity on cell performance. each microstructure was realized using the monte carlo approach with the isotropic type of gr...

Fuel flexibility is a significant advantage of solid oxide fuel cells (SOFCs) and can be attributed to their high operating temperature. Here we consider a direct internal reforming solid oxide fuel cell setup in which a separate fuel reformer is not required. We construct a multidimensional, detailed model of a planar solid oxide fuel cell, where mass transport in the fuel channel is modeled u...

Solid oxide fuel cell (SOFC) is a highly efficient power generation system that can be designed in many different geometries including planar and tubular types of cell. Although their operating performance based on the same principles, parameters may unique for each geometry. This study investigates numerically effects configuration by developing finite element method (FEM) SOFC models. The are...

long–term stability and oxidation resistance of aisi 439 ferritic stainless steel used as interconnects in solid oxide fuel cells can be improved by use of a protective coating. in this study the pack cementation method was employed to coat aisi 439 ferritic stainless steel with manganese. isothermal oxidation was conducted at 800 ºc for 200 hours in static air to investigate the role of coatin...
