FEATURES OF OPERATION OF THE SYSTEM "POLY SILICON PHOTOVOLTAIC MODULE - PROTON EXCHANGE MEMRANE ELECTROLYSER"
Given the environmental problems, the problems of energy system balancing, as well as the concept of "Green" transition of Ukraine, it is important to develop an autonomous energy-efficient solar-hydrogen system that will be able to continuously meet consumer needs.
The purpose of the work is to substantiate the operating parameters of the system "photovoltaic module - proton exchange membrane elecrtolyzer" in the conversion of solar energy into "green" hydrogen.
The objectives of the study are as follows: analysis of approaches to the implementation of solar-hydrogen systems; development of a mathematical model of a complex solar-hydrogen system and its implementation in the MATLAB; carrying an experimental study to verify the mathematical model of the solar-hydrogen complex system; analysis and comparison of the obtained results and develop recommendations for improving the efficiency of the system "photovoltaic module - proton exchange membrane electrolyzer".
Scientific provisions, conclusions and recommendations formulated in the work are based on the results of experimental research, theoretical and practical provisions on the conversion of solar energy into hydrogen energy, provisions of system analysis, statistical analysis in Microsoft Office Excel, mathematical methods for modeling energy processes in MATLAB.
A mathematical model of the system "photovoltaic module - proton exchange membrane elecrtolyzer" is obtained, which allows to analyze the influence of the intensity of solar radiation on the indicators of hydrogen yield in real conditions.
The structural block diagram of application of the autonomous system" photovoltaic module - proton exchange membrane elecrtolyzer" which consists of 4 possible options of implementation is developed. The basic electrical schemes of the photovoltaic cell, proton exchange membrane electrolyzer, complex system " photovoltaic module - proton exchange membrane elecrtolyzer", proton exchange membrane electrolyzer for removal of the characteristic of its efficiency are developed. A method for setting up an experiment and performing research on the system "polysilicon photovoltaic module - proton exchange membrane elecrtolyzer" has been developed. Ref. 5, tab. 2, fig. 9.
