Abstract
The appearance of new concepts of decentralized electricity generation and the development of renewable sources are attracting much interest for techniques of energy storage. Renewable sources are the best candidates, but the intermittent of their production needs to find effective means of storing and protecting the environment. A system coupling a photovoltaic array and an electrolyser is used to store electricity by means of a storage form of gas.
This paper presents the results of sizing a system of hydrogen production obtained through an electrolyser, powered by photovoltaic solar modules installed in Ouargla, to meet the needs of hydrogen for a fuel cell of type, PEMFC. Sizing a photovoltaic system for a given site requires knowledge of the solar radiation of the latter, unfortunately, many localities in Algeria do not have such data or the radiations are not sufficiently representative. In this study we developed a calculation program under Matlab for determining the global radiation received by a surface inclined, in a suite we have established a flowchart that helps to size the main components of the installation to produce hydrogen by introducing the necessary technical characteristics of system components and the calculated values of the global radiation for the site of Ouargla, and electric energy needs of the user.
