Control of Fuel Cell Power Systems

The problem of greenhouse gas release during power generation is widely acknowledged. Fuel cells are electrochemical devices offering clean and efficient energy production and their control is a crucial factor in making them viable for extensive use in every-day technology.§In Control of Fuel Cell Power Systems the application of fuel cells in automotive powertrains is emphasized because of the contribution to global CO2 emissions made by ground vehicle propulsion and because of the challenge presented by the control problems. Features: Overview of the physical principles and control objectives and difficulties associated with the implementation of fuel cells. System-level dynamic models derived from the physical principles of the processes involved. Formulation, in-depth analysis and detailed control design for the control of the cathode oxygen supply for a high-pressure direct hydrogen fuel cell and control of the anode hydrogen supply from a natural gas fuel processor. Multivariable controllers that attenuate restraints caused by lack of sensor fidelity or actuator authority. Real-time observers for stack variables that confer redundancy in fault detection. Examples of the assistance of control analysis in fuel cell redesign and performance improvement. Downloadable SIMULINK® model of a fuel cell for immediate use supplemented by sample MATLAB® files with which to run it and reproduce some of the book plots.§Primarily intended for researchers and students with a control background looking to expand their knowledge of fuel cells, this book will also appeal to practicing fuel cell engineers by the simplicity of its models and the application of control algorithms in real case studies. The coverage of control design will benefit scientists dealing with the electrochemical, materials and fluid-dynamic aspects of fuel cells.
