Abstract
The article considers the issues related to the development of energy technologies based on trigeneration with the use of fuel cells, which is expedient to use for additional generation of electrical energy. The possibilities of fuel cells to integrate them into traditional energy systems are shown; technological schemes using PEMFC, PAFC, and MCFC fuel cells are given. Maintaining a stable operating mode depends on temperature stability, so models of heat exchange processes are given and calculations of dynamic parameters for process stabilization under various external influences and dynamic control correction schemes are presented. The tools MatlabSimulink are used as a research tool.
