Abstract
Presents a fuel cell based power system which is modeled and analyzed under a variety of possible operating conditions. A control system based on the management of air and fuel flow regulations can be designed to provide reliable, efficient, durable and cost effective operation. In order to make this technology economically viable, feed of the air and fuel, pressure regulations, flow rates and the heat produced must be optimally controlled.
Oxygen depletion during transient reactions is the major cause of low performance and subsequent deteriorations. To address these limitations, internal subsystem reactions are modeled deliberately and examined carefully. Based on the mathematical deductions and feedback control techniques, optimal pressures and flow rates for hydrogen and oxygen are selected.
The method presented by the authors is equally valid for both Polymer Electrolyte Membrane and Solid Oxide Fuel Cells based power systems with some modifications.
