**Three Features of AEM-Type Water Electrolysis Hydrogen Production Device** 1. **Generation of High-Pressure, High-Purity Hydrogen** Hydrogen with a purity of 99.999% can be generated at a high pressure of 3.5 MPaG. The electrode reaction is the same as that of alkaline water electrolysis, but it does not use highly corrosive concentrated alkaline solutions. The cell structure, similar to PEM water electrolysis, features a membrane electrode assembly structure that offers excellent characteristics such as fast response, wide operating range, and tolerance for intermittent operation. 2. **Low Cost Achieved Without Precious Metals** AEM water electrolysis operates in a weak alkaline environment using hydroxide ions as carriers, eliminating the need for precious metals and thus achieving low costs. Additionally, the amount of water expelled from the cathode is minimal, and there is no need for electrolyte circulation, simplifying the system. 3. **Modular Design Allows for Continued Operation Even if One Unit Fails** One AEM stack can generate 0.5 Nm³ of hydrogen per hour with 2.4 kW of power, and multiple stacks can be stacked to achieve MW-class hydrogen production (210 Nm³ per hour and above). Furthermore, due to the modular design, if a single stack experiences a malfunction, only that specific stack needs to be repaired or replaced. This results in less maintenance effort compared to large hydrogen production systems.

The Toplus DHC series is a device that safely and efficiently converts leaked hydrogen into water without using any electricity. It utilizes an internal catalyst to naturally react hydrogen with oxygen in the air at room temperature, removing it as water vapor. The heat generated during the reaction promotes natural convection, further enhancing the removal efficiency. This device can safely eliminate hydrogen gas that has accumulated due to poor ventilation or equipment failure, contributing to the safety of hydrogen-related facilities and equipment. Main features: - Safely converts leaked hydrogen in enclosed spaces into water - No electricity, consumables, or fuel required - Comes with inspection certification from a third-party organization - Easy to install and maintenance-free
