Solar Photovoltaic Electrochemical Reaction System, as an instrument that can provide environmentally friendly and efficient hydrogen production capabilities, has extensive application prospects. It can provide hydrogen for green energy and can also be applied in fuel cells, energy storage systems, and industrial production.
1. Sun Tracking
The photovoltaic panel of the Solar Photovoltaic Electrochemical Reaction System is equipped with an irradiance detector, which can real-time measure the irradiance intensity of the environment where the photovoltaic panel is located. It adjusts the tilt angle of the photovoltaic panel based on irradiance intensity, maximizing the utilization of solar energy.
2. Efficient Utilization
The reactor of the Solar Photovoltaic Electrochemical Reaction System has a plate structure, effectively increasing the surface area of the electrode catalytic material, allowing the catalyst to make more effective contact with the reactants. The thin-layer structure of the reactor can reduce the problem of uneven distribution of reactants caused by low diffusion rates, reduce side reactions, and improve product selectivity. The flow system of the reactor can increase the transfer rate of electrons and protons during the catalysis process, thereby improving the reaction rate.
3. Energy Saving and Environmental Protection
The required energy for the Solar Photovoltaic Electrochemical Reaction System comes from the sun, and the reaction process does not produce greenhouse gases. Compared to other methods of electricity production such as thermal power generation, photovoltaic power generation has a lower environmental impact, making it known as "green electricity." The electricity produced is then used to generate clean energy hydrogen through photoelectrochemical or electrochemical reactions, aligning with the concept of sustainable development.
4. Real-time Monitoring
The Solar Photovoltaic Electrochemical Reaction System can real-time online monitor parameters such as irradiance intensity, voltage, current, hydrogen production, pH value, and temperature to adjust reaction conditions and optimize reaction results.
5. Graded Circulation
The Solar Photovoltaic Electrochemical Reaction System uses a miniature pump to drive liquid flow, ensuring full contact between the reaction solution and the electrode. At the same time, a gas pump is configured at the product end to timely separate and collect the gas products generated during the reaction process from the liquid, effectively improving circulation efficiency and reaction rate.
6. Flexible Design
The Solar Photovoltaic Electrochemical Reaction System can customize reactor size, circulation power system, and monitoring system according to requirements, meeting the needs of different application scenarios.
