Model Experimental of Photovoltaic-Electrolyzer Fuel Cells as a Small-Scale Power

Abstract

The purpose of this study is three to study the flow rates of H2 and O2 oxidants based on KOH concentrations at certain voltages, find the value of the best photovoltaic power at a particular test time, and find the value of fuel cells and improve the best photovoltaic-electrolyzer-fuel cell system based on calculations and the best time. The research method begins with studying the components of the PV electrolyzer and fuel cell, continuing experimental testing, and analyzing the research results. The results were obtained from the results obtained at 14.00 WIB. In electrolyzer testing, testing variations of 1 M, 2 M and 3 M molarity. The test results obtained the highest H2 and O2 gas flow rates at concentrations of 3 M, and the best efficiency at 1 M. From these data used for testing photovoltaic-electrolyzer systems -Fuel cell at 14.00 WIB with a concentration of 3 Molar, obtained the highest efficiency value of 1,847% with a power output of 2,184 Watt.
