An electrolytic cell is a device that converts electrical energy into chemical energy, widely used in hydrogen production, metal refining, wastewater treatment, and other fields. Its core principle is based on electrolysis: when direct current passes through an electrolyte solution or molten electrolyte, oxidation occurs at the positive electrode (anode) and reduction occurs at the negative electrode (cathode), thereby decomposing compounds or generating new substances. For example, in water electrolysis, oxygen is produced at the anode and hydrogen at the cathode. The entire process relies on ion migration in the electric field and catalytic action at the electrode surfaces, and its efficiency is affected by factors such as the properties of the electrolyte, electrode materials, temperature, and voltage.
The designs of electrolytic cells are diverse, including single-chamber, dual-chamber, and membrane-electrode types, to meet different reaction needs. Dual-chamber electrolyzers use ion-exchange membranes to separate the anode and cathode chambers, preventing product mixing and improving purity and safety; single-chamber electrolyzers feature a simple structure and are suitable for rapid experiments. Electrode materials such as titanium alloys or chromium-plated stainless steel enhance corrosion resistance, while flow-channel designs (e.g., serpentine or parallel channels) optimize fluid distribution and reaction efficiency.
In modern scientific research, electrolyzer technology continues to evolve. For example, ultrasound-coupled electrolyzers introduce an ultrasonic field to remove gas bubbles from electrode surfaces, reduce resistance, and, via cavitation, generate localized high temperatures and pressures to increase reaction rates and product yield. This innovation is applicable to areas such as electrocatalytic water splitting and CO2 reduction, supporting sustainable energy research.
Beijing Pofeilai Technology’s product portfolio, such as the PLS-MECF series laboratory electrolyzers and ultrasound-coupled dual-chamber electrolysis devices, is designed for research and industrial applications. These products offer significant advantages: high sealing to prevent leakage; multiple electrode sizes (e.g., 1x1 cm to 25x25 cm) and flow-channel types to support customized experiments; compatibility with anion/cation exchange membranes to suit different electrolyte environments; optional temperature-control modules (15-85°C) and viewing windows for real-time monitoring and photoelectrocatalysis research. In addition, the continuous-flow electrochemical reaction testing platform integrates intelligent control, measures temperature, flow rate, and pressure, and automatically calculates power consumption and Faradaic efficiency, simplifying data acquisition and accelerating R&D.
These products not only improve experimental precision and efficiency but also reduce energy consumption. They are suitable for laboratory-scale research such as solid electrolyte testing, perovskite batteries, and photoelectrocatalysis, helping users achieve breakthroughs in energy conversion and environmental protection. Through Pofeilai’s solutions, researchers can explore electrolysis mechanisms more efficiently and drive the development of green technologies.
