With the global energy transition accelerating, hydrogen energy, as a zero-carbon energy carrier, demonstrates immense potential in industries, transportation, and energy storage. Photovoltaic hydrogen production technology utilizes solar power to drive water electrolysis, enabling "green hydrogen" production—a critical pathway for renewable energy integration and large-scale hydrogen applications. However, this technology involves multi-stage coupling of light-electricity-hydrogen systems, necessitating educational tools to lower learning barriers and promote technical dissemination and talent development. This project aims to develop a teaching demonstration system integrating photovoltaic power generation, water electrolysis for hydrogen production, and hydrogen power generation. Through visual and interactive experimental setups, it intuitively demonstrates the full-cycle technical principles of renewable hydrogen production and utilization, advancing new energy education and research.
