| Summary: | [Objective] The hydrogen production system based on solar electrolysis of water is limited by the volatility and intermittency of solar energy, the conversion efficiency of the photovoltaic system, and the performance of the electrolysis cell. Through the performance and stability analysis of a hydrogen production system based on solar electrolysis of water, it can provide data support for technology research and development, promote the optimal design of system components, and then accelerate the commercialization process of solar electrolytic water to hydrogen technology, and help scale up the application of hydrogen energy industry. [Method] This paper proposed a solar photovoltaic (PV) cell indirectly coupled electrolyzer hydrogen production system. The research included the effects of light intensity and ambient temperature on the output performance of PV cells, analyzed the role of the storage battery in stabilizing the input power of the proton exchange membrane electrolyzer, and verified and evaluated the performance of the proposed system based on the summer climatic data of Tianjin city. [Result] Studies have shown that an increase in light intensity at a constant ambient temperature increases the PV power. When the light intensity is constant, the increase in ambient temperature will lead to a decrease in PV power generation. The battery can well stabilize the power of the electrolytic tank. [Conclusion] Through the dynamic analysis of the all-day operation of the hydrogen production system based on solar electrolysis of water, it is verified that the system contributes to the stable hydrogen production around the clock, which provides a valuable reference for the large-scale photovoltaic cell indirectly coupled electrolyzer hydrogen production system. |
