Abstract
The paper describes an experimental model of a hybrid power source (HPS) on the basis of solid oxide fuel cells (SOFC) being developed by the authors. HPS includes generating system, power storage system, pairing system and an active-adaptive control system. Generation system includes a reformer and a modular electrochemical generator based on SOFC. The storage system consists of a capacitive storage (CS) and accumulation batteries (AB). Accumulation batteries are made of alkaline nickel-cadmium batteries with improved power characteristics. A converter of current distribution (CCD) makes the basis of HPS pairing system. The authors developed a schematic diagram of CCD with three DC/DC upconverters. To implement an active-adaptive control system an algorithm of HPS operation was developed. The investigation of currents redistribution modes was carried out on the HPS simulation computer model developed by the authors. The research made it possible to determine the mode of stabilization of generated power, providing maximum SOFC utilization ratio.
