The electrolyzer is the core component of the hydrogen inhaler (hydrogen inhalation equipment), which directly determines the hydrogen production efficiency, hydrogen purity, safety and user experience of the equipment. Key role: The electrolyzer achieves instant hydrogen generation through the coordinated work of electrodes, electrolytes and membranes, without the need for external hydrogen storage equipment. Here is a brief introduction to two commonly used household hydrogen technologies.
The purity of hydrogen produced by different types of electrolyzers varies significantly
1. PEM electrolyzer: purity reaches 99.9995%, and the impurities are mainly water vapor, which is suitable for direct inhalation.
2. Alkaline electrolyzer: purity is about 99.98%, but corrosive gases (such as KOH vapor) may remain, requiring additional purification.
High-purity hydrogen can prevent the human body from inhaling impurities and ensure health and safety.
Adapt to dynamic power
1. PEM electrolyzer has a millisecond response speed, which can quickly adjust the hydrogen production to match the start and stop requirements of the hydrogen inhaler.
2. The power adjustment of the alkaline electrolyzer is slow (minute level), and it is necessary to maintain ≥20% of the rated power to prevent hydrogen back-mixing explosion.
Determining factors for safety
1. Anti-corrosion design: Alkaline electrolyzers may release corrosive gases due to the use of KOH solution, so they need to be strictly sealed; PEM electrolyzers are non-corrosive and more suitable for human contact scenarios.
2. Anti-gas crosstalk: Patented technologies (such as membrane electrode adhesion sealing frame) can prevent the risk of hydrogen permeation caused by membrane electrode deformation.
3. Low-voltage operation: Home hydrogen absorption machines use low-voltage electrolysis (usually <60V) to avoid leakage and explosion hazards of high-voltage electrolysis
Key guarantees for user experience
1. Compactness and silence: PEM electrolyzers are small in size and have no pump noise, making them suitable for home use; alkaline electrolyzers require an auxiliary circulation system and are noisy.
2. Ready to use: PEM electrolyzers support cold start (hydrogen production in seconds), while alkaline cells need to be preheated to above 60°C, which takes a long time.
3. Maintenance-free design: The new hydrogen absorption machine electrolyzer uses a titanium plate + sealing frame structure, and the membrane electrode is not easily deformed after water loss, and the maintenance cycle is extended.
Suyzeko Hydrogen Machine Principle---PEM Electrolysis Technology
During PEM electrolysis, water is electrochemically decomposed into hydrogen and oxygen. In this process, water molecules first break down on the anode side, producing oxygen, protons (H⁺), and electrons (e⁻). The resulting oxygen is discharged from the anode surface, the remaining protons reach the cathode side through the proton conductive film, and the electrons reach the cathode side through the external circuit. On the cathode side, protons and electrons recombine to produce hydrogen.
Electrolysis cell structure diagram
The main components of the PEM electrolyzer are the membrane electrode assembly (composed of membrane and anode and cathode materials), the gas diffusion layer, the separation plate (bipolar plate) and the end plate.
End plate: aluminum alloy
Proton exchange membrane: US DuPont

Wiring board: pure titanium
Diffusion layer: pure titanium
Catalyst: anode loaded iridium, cathode loaded platinum
Suyzeko electrolyzer advantages:
• Proton exchange membrane: High performance perfluorosulfonic acid membrane (such as DuPont Nafion or similar high-end membrane) with high proton conductivity, low gas permeability, excellent chemical stability and long life span.
• Catalyst: The use of precious metals (such as iridium, platinum) as a catalyst, high activity, strong stability, significantly improve the efficiency of electrolysis.
• Bipolar plate: titanium + precious metal platinum coating, strong corrosion resistance, reduce contact resistance, extend service life.
• Process technology: Precision manufacturing (such as nanoscale catalyst dispersion technology, zero-pitch membrane electrode components, etc.), ensure efficient reaction status.
Technological innovation
1. Anti-deformation membrane electrode: The membrane electrode is fixed to the titanium plate through the sealing frame bonding technology to avoid curling and deformation during disassembly, and maintenance-free.
2. Gradient titanium mesh design: Multi-layer titanium mesh (with reduced pore size gradient) is used to optimize water flow distribution and improve electrolysis efficiency.
3. Integrated flow channel optimization: Diagonally arranged water inlet/hydrogen outlet channels avoid gas-liquid blockage and ensure stable hydrogen output
