Abstract: This study is a real model which aims to show how the elements of the photovoltaic system, electrolyzer and fuel cells come to overcome and reform intermittent and fluctuating renewable energy. Some challenges of PV cells are sun set, cloudy skies, snow and dust. These environmental conditions block sunlight capture via photovoltaic, so, the electrolyzer produces gases and stores it via hydrogen tank. During normal day, PV generates electricity to feed the load, but if the sky is cloudy or raining or we have a lack of generation for any reason, the fuel cells will generate power to feed load directly, and this fuel will be the gases that were produced and stored via the electrolyzer the previous day.

Keywords: Photovoltaic, electrolyzer and fuel cells.
