Analysis of Design Parameters in Anode‐Supported Solid Oxide Fuel Cells Using Response Surface Methodology

Abstract

Achieving high performance from a solid oxide fuel cell (SOFC) requires optimal design based on parametric analysis. In this paper, design parameters, including anode support porosity, thicknesses of electrolyte, anode support, and cathode functional layers of a single, intermediate temperature, anode‐supported planar SOFC, are analyzed. The response surface methodology (RSM) technique based on an artificial neural network (ANN) model is used. The effects of the cell parameters on its performance are calculated to determine the significant design factors and interaction effects. The obtained optimum parameters are adopted to manufacture the single units of an SOFC through tape casting and screen‐printing processes. The cell is tested and its electrochemical characteristics, which show a satisfactory performance, are discussed. The measured maximum power density (MPD) of the fabricated SOFC displays a promising performance of 1.39 W cm–2. The manufacturing process planned to fabricate the SOFC can be used for industrial production purposes.

Environmentally Friendly Flux Growth of High-Quality, Idiomorphic Li5La3Nb2O12 Crystals

“…Green energy technologies, such as small-scale hydro and wind power technologies, geothermal generation, solar cells, , fuel cells, , and lithium-ion batteries (LIBs), − have recently garnered the attention of many researchers because they provide an effectual approach to solve the problem of environmental warming caused by the release of greenhouse gases from vehicles and during the production of electricity. In particular, LIBs have been investigated for use as power sources in electric vehicles, hybrid electric vehicles, and plug-in hybrid electric vehicles because of the high energy density resulting from their high discharge voltages. , Among LIBs, all-solid-state LIBs − that use inorganic oxides as solid-electrolyte materials, such as Li 5 La 3 Nb 2 O 12 , , Li 3 x La 2/3– x TiO 3 (0.03 < 3 x < 0.75), , Li 1.5 Al 0.5 Ge 1.5 (PO 4 ) 3 , and Li 7 La 3 Zr 2 O 12 , have attracted attention because of their safety and stability.…”

Processing of composites based on NiO, samarium-doped ceria and carbonates (NiO-SDCC) as anode support for solid oxide fuel cells

“…Cells with anode supports are more advantageous than electrolyte or cathode supported cells due to improved reliability, high stability and reduced electrolyte thickness. The anode supported cells may also significantly reduce the resistance between the electrolyte interfaces [1][2][3]. Furthermore, high electrical conductivity is mainly considered during the selection of materials suitable for manufacturing SOFC anodes.…”

INFLUENCE OF SINTERING TEMPERATURE ON NiO-SDCC ANODE FOR LOW-TEMPERATURE SOLID OXIDE FUEL CELLS (LT-SOFCs)

“…Anode-supported SOFCs with a planar configuration are generally favoured over electrolyte-supported SOFCs because of low operating temperatures, thereby reducing manufacturing costs and widening the choice of materials [1][2][3]. Furthermore, anode-supported cells are more reliable, stable, and able to reduce the electrolyte thickness and resistance between electrolyte interfaces [4][5][6].…”
