Experimental Investigation of a Solid Oxide Fuel Cell Stack using Direct Reforming Natural Gas
In this study, a solid oxide fuel cell (SOFC) stack has been successfully fabricated and tested by using direct natural gas. The main objective of this research was to achieve optimal long-term performance of the SOFC stack without carbon deposition by using low-cost natural gas as a fuel. The stack configuration was improved by a new interconnect design and made of cost-effective raw materials...
متن کاملEfficiency Analysis of Planar Solid Oxide Fuel Cell at Direct Internal Reforming Conditions
A detailed model is presented for the analysis of temperature, species concentration, and current density profiles as well as the efficiency and power density of a planar solid oxide fuel cell at direct internal reforming condition. The model describes the interactions of mass transport, heat transport, heterogeneous chemistry, and electrochemistry. The heterogeneous chemistry model for the cat...
متن کاملModeling and Analysis of a Solid Oxide Fuel Cell Based Trigeneration System with an Oxygenated Fuel by Using an Exergoeconomic Methodology for Power, Heating and Cooling Production
In the present study, thermo-economic analysis of a combined solid oxide fuel cell (SOFC) with a gas turbine, a generator-absorber heat exchanger (GAX) and heating process heat exchanger for heating, cooling and power production as a tri-generation system is conducted. Also, an external steam reformer is applied to convert methanol as oxygenated fuel to hydrogen for the electrochemical process ...
متن کاملSimulation of a Solid Oxide Fuel Cell with External Steam Methane Reforming and Bypass
Fuel flexibility is a significant advantage of solid oxide fuel cells (SOFCs) and can be attributed to their high operating temperature. The eligibility of a combined heat and power (CHP) system has been investigated as a new power generation methode, in this study. Natural gas fueled SOFC power systems via methane steam reforming (MSR) yield electrical conversion efficiencies exceeding 50% and...
متن کاملCFD analysis of a solid oxide fuel cell with internal reforming: Coupled interactions of transport, heterogeneous catalysis and electrochemical processes
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...
