Dynamic simulation of an anode-supported tubular SOFC is performed to study the transients of current and the transport fields in the cell. The time constants of the system are studied and the possible explanations for their variation within the cell and at various overpotentials are presented. It was observed that the gain of the system varies depending upon the operating conditions of the sys...

Structure property relationships in two series of BaO-ZnO-La2O3-Al2O3-B2O3-SiO2 glasses have been investigated to assess their suitability for use as sealants solid oxide fuel cell (SOFC) applications. Density, mechanical properties, thermal and electrical properties a function composition. Raman Fourier transfer infra-red spectroscopies were undertaken obtain insights into the glass structure....

This study shows the design of a new hybrid power generation system, photovoltaic panel (PV)–coupled solid oxide fuel cell (SOFC) and gas turbine (GT)–electrolyser. Three objectives (cost, pollutant emissions, and reliability), which are usually in conflict, are considered simultaneously. The design of a hybrid system, considering the three mentioned objectives, poses a very complex problem of o...

In this study, the effect of recycling fuel cell products on the performance of a solid oxide fuel cell and gas turbine (SOFC-GT) hybrid system was investigated. Three types of products recycling are considered: cathode products recycling (CPR), anode products recycling (APR), and both cathode and anode products recycling (BACPR). In the present work,   operating temperature and  limiting curre...

Due to the high operating temperature of solid oxide fuel cells (SOFC), system efficiency depends on efficient thermal integration and effective construction configuration. In this study, nine configurations design were investigated evaluate possible improvement with energy separation devices. The models developed under Matlab/Simulink® platform Thermolib® module. reference layout simulation in...

Ni alloys are examined as redox-resistant alternatives to pure for solid oxide fuel cell (SOFC) anodes. Among the various candidate alloys, Ni–Co selected due their thermochemical stability in SOFC anode environment. alloy cermet anodes prepared by ammonia co-precipitation, and electrochemical performance microstructure evaluated. exhibit high durability against redox cycling, whilst current-vo...

Abstract A solid oxide fuel cell (SOFC) with a liquid antimony anode (LAA) is potential energy conversion technology for the use of impurity-containing fuels. Atmospheric plasma spraying (APS) has become promising LAA-SOFC preparation method because its economy and convenience. In this paper, button SOFCs different cathode materials ratios pore former were prepared by APS operated at 750 °C. Th...

The solid oxide fuel cell (SOFC) system is complicated because the characteristics of gas, heat, and electricity are intricately coupled. During operation system, problems such as frequent failures a decrease in stack’s performance have caused SOFC to work less well greatly shortened SOFC’s practical life. As such, it essential accurately forecast its remaining useful life (RUL) make last longe...
