Photovoltaic direct drive and photoelectrocatalytic hydrogen production technologies have made significant progress in mechanistic research. However, researchers often face a formidable hurdle in the process of advancing towards technology development and pilot production.
For a long time, the setup of such experimental devices has often presented the following problems: the light source, reactor, gas path control, and data acquisition modules often perform their own functions, relying on manual connection and monitoring. This not only leads to low system integration and large space occupation, but also poses a huge challenge to error control and safety protection during the experiment. In response to this situation, PLR-PVERS100-O1 photovoltaic hydrogen production integrated device has been launched. This is a complete set of R&D equipment that integrates photovoltaic direct drive, closed-loop control of the entire process and automated data acquisition.
1. Multi-path parallel operation: Achieving a large-scale leap in photovoltaic direct-drive hydrogen production
PLR-PVERS100-O1 photovoltaic hydrogen production integrated device has a built-in 200×200 mm reactor and can be expanded to 16 250×250 mm reactors. This highly modular design allows researchers to conduct outdoor pilot-scale experiments in the same environment, and also to directly simulate a large-scale continuous hydrogen production process through multi-path parallel operation. Meanwhile, unlike traditional photovoltaic systems that first convert solar energy into electrical energy and store it in batteries before powering the reactor, this device directly drives the photovoltaic output to the corresponding reactor, establishing a direct correlation between solar irradiance, photovoltaic output current, and reactor product generation. This makes it more suitable for photovoltaic-electrochemical coupling, solar fuel preparation, and outdoor real-world demonstrations. 2. Intelligent Closed-Loop Control and Data Link Integration The device uses a Siemens PLC system, achieving deep integration of "motion control" and "high-precision data acquisition." Automated Control: One-button start/stop for the entire hydrogen production process; real-time adjustment of variables such as electrolyte circulation and light source power to ensure highly consistent conditions for long-term experiments. Research-Grade Data Acquisition: Real-time synchronous recording of pressure, temperature, flow rate, and irradiance. All parameters are no longer isolated scattered points, but form a complete and exportable data chain, providing traceable evidence for paper reproduction and process optimization.
3. Full-Dimensional Protection: Entrusting Safety to the System, Returning Energy to the Research
In complex environments involving high-voltage electrical equipment and flammable gases, the device constructs a rigorous physical and logical dual interlock.
Long-term Light Source Protection: Even in extreme situations such as sudden cooling water interruption during unattended operation at night, the system can trigger automatic overheat protection to prevent damage to the expensive light source.
Dynamic Gas Path Monitoring: Equipped with precision sensors and pressure regulation and relief mechanisms throughout the entire process, ensuring gas path safety within the 0~1 MPa working pressure range in real time.
Environmentally Friendly Design: For highly corrosive electrolyte systems, PP/PTFE corrosion-resistant pipes and leak-proof structures are used, supplemented by filter clogging warnings, ensuring a clean and safe laboratory environment.
4. Integrated Enclosure and Quick-Response Design
The entire unit adopts an integrated enclosure with a floor space of only a few square meters. Standardized pipe interfaces and quick-connect design greatly simplify equipment deployment and subsequent maintenance. Complete installation and commissioning guidelines are provided to ensure the equipment is ready to use upon arrival.
5. Compliance and Certification, Domestic Substitution
Product design strictly follows multiple national standards such as GB/T 19774-2005, fully covering the needs of domestic production, effectively replacing imported similar products, and possessing excellent cost performance and localized service response advantages.
