Book excerpt: Fuel cells are electrochemical devices that oxidize fuel without combustion to convert directly the fuel's chemical energy into electricity. The solid oxide fuel cell (SOFC) is distinguished from other fuel cell types by its all solid state structure and its high operating temperature (1,000 C). The Westinghouse tubular SOFC stack is process air cooled and has integrated thermally and hydraulically within its structure a natural gas reformer that requires no fuel combustion and no externally supplied water. In addition, since the SOFC stack delivers high temperature exhaust gas and can be operated at elevated pressure, it can supplant the combustor in a gas turbine generator set yielding a dry (no steam) combined cycle power system of unprecedented electrical generation efficiency (greater 70% ac/LHV). Most remarkably, analysis indicates that efficiencies of 60 percent can be achieved at power plant capacities as low as 250 kWe, and that the 70 percent efficiency level should be achievable at the two MW capacity level. This paper describes the individual SOFC, the stack, and the power generation system and its suitability for distributed generation.

Download or read book Transient Analysis of a Solid Oxide Fuel Cell/ Gas Turbine Hybrid System for Distributed Electric Propulsion written by Venkata Adithya Chakravarthula and published by . This book was released on 2016 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gas turbine technology for aerospace applications are approaching limits in efficiency gains as increases in efficiency today occurs in very small increments. One limitation in conventional gas turbine technology is the combustion process, which destroys most of the exergy in the cycle. To address this limitation in a traditional Brayton power cycle, a hybrid system which is integrated with Solid Oxide Fuel Cell (SOFC) and gas turbine is developed. Hybrid systems involving fuel cells have better efficiencies than conventional power generation systems. Power generation systems with improved performance from low fuel utilizations and low maintenance costs are possible. The combination of a SOFC fuel cell with a gas turbine has shown higher efficiencies than conventional gas turbine systems due to the reduction of exergy destruction in the heat addition process. A one-dimensional dynamic model of a Solid Oxide Fuel Cell (SOFC) integrated with a gas turbine model to develop an efficient electrical power generation system for aviation applications is investigated. The SOFC - Combustor concept model was developed based on first principles with detailed modeling of the internal steam reformer, electrochemical and thermodynamics analysis is included. Initially, a detailed investigation of internal steam reformer kinetics is presented. The overall purpose of this thesis is to analyze the performance of the hybrid SOFC-GT system for both on-design and off-design operation in an aerospace application. Transient analysis is performed to understand the uncertainties in the SOFC temperatures and hybrid system; control and stability with sudden transientiiichanges of the system (rapid throttle changes, environment changes like climb). Finally, SOFC model integrated with a compressor and turbine model and investigation on the overall performance of the innovative hybrid thermodynamic cycle is presented. The SOFC hybrid system has a lower power density at sea level compared to a turbo-generator, but in a typical commercial flight the SOFC hybrid system outperforms the turbo-generator in both endurance and power-to-weight ratio at cruising altitude.

Available in PDF, EPUB and Kindle. Book excerpt: Distributed generation is defined as the installation and operation of electric power generation units connected directly to the distribution network. The fundamental idea of distributed generation, is to situate generation close to the load, therefore on the distribution network or on the customer side of the meter. A fully mature fuel cell industry constitutes a potential opportunity to electric utilities. It could meliorate the technical and financial performance of existing distribution lines by improving service quality and reliability. When fuel cells connect to the power system, both the owner of the energy resource and the central power system benefit. Reliability increases for both because they can support each other. However, the interconnection of fuel cell plants to the grid is still hindered by restrictive conditions and procedures for grid connection. Problems arise with regard to determination of the point of connection, safety and stability issues. Most important it is needed to establish a standardized technical interface for allocation of connection that take into account possible positive effects of distributed generation on transmission and distribution losses. With respect to residential applications, in Chapter 1 are presented regulations, codes, standards and technical aspects of grid connection. A group of contributions in this book is dedicated to some aspects of control. Chapter 2 focuses on the operation and control of the solid oxide fuel cell distributed generator for stationary power application. In Chapter 3, the control of grid-connected fuel cell-based distributed generation systems is discussed first. Then, the load transient mitigation techniques for stand-alone systems are also investigated. Chapter 4 discusses various issues related to system penetration, system operation and control. The next chapters deal with analyses of energy systems. Chapter 5 presents energy system analysis tools. By use of the tools, it is possible to analyze an energy system in which fuel cells provide different services. In Chapter 6, a method for forest biomass exploitation for energy production purposes is presented. This work addresses an hybrid system based on the coupling of a gas turbine with a high temperature solid oxide fuel cell. Chapter 7 focuses on a suite of software modules for computer-aided modeling of solid-polymer fuel cells. Chapter 8 develops nonlinear models of solid oxide fuel cell. And finally, Chapter 9 describes artificial intelligence applications to fuel cell inverters. As editor, I would like to thank all authors for their contributions. I hope that you, the reader, will profit from the results presented in this special review book. It may promote you to join the fascinating field of fuel cell and distributed generation.
