Design of a Solar-Hydrogen-Fuel Cell Unit for passive lighting and driving Small Electrical Loads in Residential Buildings of Saudi Arabia

摘要

The present paper proposes a new imaging of a Solar-Hydrogen-Fuel cell-stand alone-unit for passive lighting and driving small electrical loads in residential buildings of Saudi Arabia in order to save energy consumption. The designed system consists of a solar panel, PEM-electrolyzer for hydrogen production, hydrogen fuel cell and miscellaneous. The proposed system can be switched between day and night in order to obtain a continuous operation. The daylight cycle works directly from sun energy, while the night cycle is dependent on the storage of solar energy in form of hydrogen energy. The proposed stand-alone unit can become widely utilized not just for driving small electrical loads but for industrial process applications where different loads are required. The proposed system can be considered as a very promising candidate for transportation applications since it is compact, lightweight and delivers the required power.
