1、 Core principle: electrolysis of water decomposition
The core technology of the hydrogen rich water cup actually comes from the middle school chemistry class - electrolysis of water. When the cup is powered on:
Positive electrode (anode) produces oxygen: 2H ₂ O → O ₂ ↑+4H ⁺+4e ⁻
The negative electrode (cathode) produces hydrogen gas: 2H ₂ O+2e ⁻ → H ₂ ↑+2OH ⁻. Through this reaction, ordinary water becomes "hydrogen rich water" containing hydrogen gas.
2、 Disassembly of key components
Electrode pads: usually made of precious metals such as platinum/titanium to avoid electrode corrosion
Proton exchange membrane: Advanced cups will be equipped to prevent hydrogen and oxygen from mixing (important safety design!)
Control circuit: Adjust the current to determine the hydrogen production concentration (usually 0.5-1.6ppm)
Sealing structure: using aviation grade sealing technology to delay hydrogen escape
3、 Differences in technological schools
Type, working principle, characteristics, SPE electrolysis, solid-state polymer electrolysis, highest purity, expensive price, PEM electrolysis, proton exchange membrane electrolysis, good safety, mainstream product, alkaline electrolysis, low cost of adding electrolyte, but may produce by-products
4、 Three Cold Knowledge
Hydrogen insoluble: 1L of water can dissolve up to 1.6mg of hydrogen at room temperature and pressure, so those who promote "ultra-high concentration" are mostly misleading
Bubble mystery: Some products intentionally create large bubbles, but in fact, the bubbles cannot be seen after the hydrogen gas dissolves
PH value change: After electrolysis, water will temporarily become weakly alkaline (pH 7.5-9.5), but it will reduce upon contact with air
5、 Precautions for use
Avoid using mineral water (minerals can damage electrodes)
After each use, dry the toast body
Suggest using distilled water or purified water
Stop immediately if the electrode turns black
