This system consists of solar photovoltaic panels (PVs) a controller an electrolyzer a metal hydride hydrogen tank used for hydrogen production and storage and Proton Exchange Membrane Fuel Cell (PEMFC) for electricity storage. Dead state temperature is taken as 0 ºC. The results revealed that the PEMFC had the highest energy efficiency of 53.28%. Exergy efficiencies of the solar PV panel the electrolyzer and the PEMFC were determined to be 9.66% 60% and 29.39% respectively. The exergetic sustainability index of the electrolyzer had the maximum value of 2.501. © 2023 Elsevier B.V.
