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 کاملEnergy Analysis of Pressurized Solid Oxide Fuel Cell Combined Power Turbine
Solid oxide fuel cells have been considered in the last years as one of the most promising technologies for very highefficiency electric energy generation from hydrogen or other hydrocarbons, both with simple fuel cell plants and with integrated gas turbine-fuel cell systems. In the present study, a detailed thermodynamic analysis has been carried out. Mass and exergy balances are performed not...
متن کاملTwo-Layered Real-Time Optimization of a Solid Oxide Fuel Cell Stack
The optimal operation of a solid oxide fuel cell stack is addressed in this paper. Real-time optimization, performed at a slow time scale via constraint adaptation, is used to account for uncertainty and degradation effects, while model-predictive control is performed at a faster time scale to reject process disturbances and to safely adapt the system to the specified output constraints followi...
متن کاملPerformance of Reversible Solid Oxide Cells: A review
It was shown about 25 years ago that solid oxide fuel cells (SOFC) could also work in the solid oxide electrolyser cell (SOEC) mode. Electrolysis of both water (steam) and CO2 was demonstrated. During the 1990'ies very little electrolysis work was reported in the open literature, whereas an enormous amount of results on the SOFC R&D appeared. Recently, the increasing interest in hydrogen produc...
متن کاملA New Sensitivity Study of Thermal Stress Distribution for a Planar Solid Oxide Fuel Cell
Converting chemical energy into electricity is done by an electro-chemical device known as a fuel cell. Thermal stress is caused at high operating temperature between 700 oC to 1000 oC of SOFC. Thermal stress causes gas escape, structure variability, crack initiation, crack propagation, and cease operation of the SOFC before its lifetime. The aim of this study is to presen...
