In this paper, a nonlinear offline model of the solid oxide fuel cell (SOFC) is built by using a radial basis function (RBF) neural network based n a genetic algorithm (GA). During the process of modeling, the GA aims to optimize the parameters of RBF neural networks and the optimum alues are regarded as the initial values of the RBF neural network parameters. Furthermore, we utilize the gradie...

Based upon the thermodynamic simulation of a biogas-SOFC integrated process and costing its elements, present work examines economic feasibility biogas-SOFCs for combined heat power (CHP) generation, by comparison their performance against conventional biogas-CHP with internal combustion engines (ICEs), under same assumptions. As well as issues scale an SOFC’s cost, examined in literature, stud...

Record high performance and longevity is reported for a butane-fueled low-temperature-operating solid oxide fuel cell (LT-SOFC). Affordable catalysts, Cu CeO 2 , were incorporated into thin-film-based SOFC to enable this remarkable enhancement.

This paper presents a hydrogen powered hybrid solid oxide fuel cell-steam turbine (SOFC-ST) system and studies its optimal operating conditions. This type of installation can be very appropriate to complement the intermittent generation of renewable energies, such as wind generation. A dynamic model of an alternative hybrid SOFC-ST configuration that is especially suited to work with hydrogen i...

The idea of a fuel cell was first discovered in 1839 by Christian Friedrich Schönbein [64] and William Grove [27]. Independently from each other they provided the foundation for the development of many different kinds of fuel cells. Today’s fuel cells are mostly classified by the type of electrolyte used in the cells. The most common types are polymer electrolyte fuel cells PEFC (developed by W...

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 (...

Internal dry reforming (IDR) of methane for biogas-fed solid oxide fuel cell (SOFC) applications has been experimentally investigated on planar Ni-GDC (cermet anode) electrolyte-supported cells. This study focuses the effect CO2 concentration, current density, operating temperature, and residence time internal reforming. A single is fed with different CH4/CO2 mixture ratios between 0.6 1.5. Ext...

Development of solid oxide fuel cell (SOFC) anode with high resistance to coking and sulfur poisoning is highly desirable for the direct application natural gas in SOFC. Herein, a (Cu, Sm)CeO2 anchored Cu nanoparticles has been prepared. Most particle size ranges from 20 50 nm, which can increase conductivity catalytic activity anode. The Cu/CSCO10 supported exhibits maximum power density 404.6...

Direct internal reforming in solid oxide fuel cell (SOFC) results in increased overall efficiency of the system. Present study focus on the chemical and electrochemical process in an internally reforming anode supported SOFC button cell running on humidified CH4 (3% H2O). The computational approach employs a detailed multi-step model for heterogeneous chemistry in the anode, modified Butler–Vol...

The cathode/electrolyte LSCF48/YDC15 couple is a building block of a new innovative and competitive design of a high temperature fuel cell, operating in the range between 600 and 700°C. It is based on the idea for a junction between a proton conducting SOFC (PCFC) anode/electrolyte part and a SOFC cathode/electrolyte part through a mixed H and O conducting porous ceramic membrane. Thus, in this...
