Performance modeling and parametric investigation of a solid oxide fuel cell (SOFC)
In his paper, performance modeling and parametric study of a tubular solid oxide fuel cell (SOFC) fed by hydrogen was conducted. The components of the fuel cell system and its reactions were entirely modelled and an electrochemical analysis done for it. A variety of modeling parameters including temperature, working pressure and the air mass- flow rate have been investigated in order to observe...
متن کاملFactors governing oxygen reduction in solid oxide fuel cell cathodes.
Recent worldwide interest in building a decentralized, hydrogen-based energy economy has refocused attention on the solid oxide fuel cell (SOFC) as a potential source of efficient, environmentally friendly, fuel-versatile electric power. Due to its high operating temperature, the SOFC offers several potential advantages over polymer-based fuel cells, including reversible electrode reactions, lo...
متن کاملModel Reduction of a Solid Oxide Fuel Cell (SOFC) for Control Purposes
Fuel cells belong to an avant-garde technology family for a wide variety of applications including micro-power, transportation power, stationary power for buildings and other distributed generation applications. The first objective of this contribution is to find a suitable reduced model of a Solid Oxide Fuel Cell (SOFC). The derived reduced model is then used to design a state estimator. I...
متن کاملTransient studies of perovskite anode catalyst for a direct CH4 Solid Oxide Fuel Cell
Introduction: The direct use of CH4 as the feed to the solid oxide fuel cell (SOFC) will allow elimination of a reformer, simplifying the SOFC system and decreasing the system cost [1]. The overall reaction on the anode catalyst in the direct CH4 SOFC is the electrochemical oxidation of CH4: CH4 + 4O CO2 + 2H2O + 8e. Due to the nature of hydrocarbon reactions at high temperature and the reducin...
متن کاملDynamic simulation and analysis of a Solid Oxide Fuel Cell (SOFC)
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...
