Ecological Systems and Devices Annotation << Back Development of Adaptive Energy Management Strategy for Hydrogen Fuel Cell Based Power Source Lipuzhin I.A., Shalukho A.V., Shuvalova Yu.N. The concept of hydrogen energy development has become widespread throughout the world and is one of the stages of the strategy for reducing greenhouse gas emissions. This is explained by the fact that hydrogen produced by electrolysis of water using electricity from renewable energy sources and using nuclear power plants is considered environmentally friendly. The conversion of hydrogen energy into electricity to power transport or stationary consumers occurs in hydrogen fuel cells, among which the most widespread are low-temperature proton-exchange membrane fuel cells (PEMFC). Since the power of PEMFC stack is limited, it is necessary to combine several stacks for parallel operation to create powerful power source. The effi ciency of multistack fuel cell system directly depends on the choice of the optimal power sharing strategy between PEMFC stacks, which directly affects the total hydrogen consumption of the system. The article describes the operating principle of PEMFC and the factors affecting the change in PEMFC characteristics during operation. Using the results of simulation modeling, it is shown that the choice of the optimal power sharing strategy depends on the type of characteristics of the PEMFC used in the multistack. To reduce the hydrogen consumption of the system, it is necessary to develop an adaptive energy management strategy, which will take into account changes in the PEMFC characteristics in a real time.
