This conceptual study proposes a hybrid energy system that integrates a 100W PV solar panel with hydrogen storage, electrolyzer, and fuel cell technologies to generate reliable power for household usage in developing countries. The system's key components are evaluated for performance, efficiency, and cost-effectiveness.

During daylight hours, the PV solar panel generates electricity, and any excess power is stored as hydrogen gas using an electrolyzer. The stored hydrogen is then used to power a fuel cell to generate electricity during periods of low solar radiation. The hydrogen storage tank and the electrolyzer are optimized to ensure efficient hydrogen production and storage, while the fuel cell is optimized to provide the required power output and reliability.

The results show that the proposed system is cost-effective and has the potential to provide reliable power to households in developing countries. While further experimental work is necessary to validate the design and optimize the system's performance, the study provides a useful reference for designing and implementing similar systems in regions with limited electricity access and abundant renewable energy sources. The proposed system can improve living standards and promote economic development in these regions.
