Product Description

 

What is a MEA technology hydrogen water bottle ?

A membrane - electrode assembly (MEA) mainly consists of a proton - exchange membrane, a catalyst layer (usually containing catalysts such as platinum), etc., but it is not simply a proton - exchange membrane plus a platinum coating.

 

1. Proton - exchange membrane (PEM)

 

• It is one of the core components of the membrane - electrode assembly. The proton - exchange membrane is selectively permeable, allowing only protons (hydrogen ions, H) to pass through and preventing the direct transfer of electrons and other gases (such as hydrogen and oxygen). For example, in a fuel cell, it enables protons generated at the anode to cross the membrane to the cathode, forcing electrons into the external circuit, thereby generating an electric current. A common material for proton - exchange membranes is perfluorosulfonic acid resin, such as the Nafion series membranes of DuPont.

 

1. Catalyst layer

 

• The catalyst layer is the site where electrochemical reactions occur. In many application scenarios (such as fuel cells), platinum (Pt) is a commonly used catalyst. Platinum can effectively reduce the activation energy of the reaction and accelerate the electrode reaction. However, in addition to platinum, there are other components. Usually, platinum nanoparticles are highly dispersed on a carbon black carrier and then mixed with an ionomer (such as perfluorosulfonic acid ionomer) to make catalyst ink. This ink is coated on both sides of the proton - exchange membrane to form the catalyst layer. This is because a simple platinum coating is difficult to achieve the desired catalytic effect. The carbon black carrier can increase the specific surface area of the catalyst, and the ionomer helps in proton conduction, thereby synergistically improving the catalytic efficiency.

 

1. Gas - diffusion layer (GDL)

 

• This is also an important part of the membrane - electrode assembly. It mainly plays the roles of supporting the catalyst layer, providing gas channels and electron - conduction channels. The gas - diffusion layer is generally composed of porous carbon materials, enabling the reaction gases (such as hydrogen and oxygen in a fuel cell) to smoothly diffuse to the surface of the catalyst layer and also conduct the electrons generated by the catalyst layer.

 

Therefore, the membrane - electrode assembly is a relatively complex multi - layer structure combination, with each part working in coordination to achieve high - efficiency electrochemical performance.

Why should you select the MEA technology hydrogen bottles?
 

1. Analysis of the MEA Components
   • The membrane - electrode assembly (MEA) is indeed a crucial part of many electrochemical devices such as fuel cells and electrolyzers. As mentioned, it consists of a proton - exchange membrane, a platinum - catalyst coating, and a gas - diffusion layer.
   • The proton - exchange membrane allows the transport of protons (H) while separating the anode and cathode compartments. The platinum - catalyst coating facilitates the electrochemical reactions (e.g., in a fuel cell, the oxidation of hydrogen at the anode and the reduction of oxygen at the cathode). The gas - diffusion layer helps in the diffusion of reactant gases (like hydrogen and oxygen) to the catalyst layer and also in the conduction of electrons.
2. Safety and Reliability of Hydrogen - generating Cups
   • For hydrogen - generating cups, the quality of the membrane - electrode technology is of great importance. Good membrane - electrode technology is essential for safety and reliability.
   • If the voltage increases during long - term use, it may indicate problems such as electrode degradation or membrane damage. Unstable voltage can lead to inefficient operation and potential safety hazards.
   • Regarding the total dissolved solids (TDS) in water, a significant increase after electrolysis may suggest that other substances are being released into the water due to electrode corrosion or membrane leakage. This can affect the quality of the generated hydrogen and the safety of the device.
   • The concentration of hydrogen generated by electrolysis is also a key factor. A significant decrease in hydrogen concentration over time implies that the efficiency of the electrolysis process is deteriorating, which may be due to problems with the membrane - electrode assembly, such as catalyst deactivation or membrane fouling.
3. Overall Significance
   • These requirements for good membrane - electrode technology are crucial for the proper functioning of hydrogen - generating cups. Meeting these criteria helps to ensure that the device can produce high - quality hydrogen safely and reliably over an extended period. It also reflects the importance of stable electrochemical performance and material integrity in such applications.

Are hydrogen cups with membrane - electrode technology necessarily good hydrogen - rich water cups?

The answer is no. Cups with membrane - electrode technology surely achieve hydrogen - oxygen separation, which
is beyond doubt. However, not all cups with this technology are good. Whether a hydrogen - rich water cup is good
depends on the maturity of the membrane - electrode technology, which is crucial.

 

Poor - quality membrane - electrode technology may bring the following potential risks. During long - term electrolysis,
the platinum - catalyst coating of the membrane - electrode may peel off. Once this happens, the voltage will increase,
and almost all the by - products will enter the water, such as ozone, residual chlorine, and heavy metals.

How todistinguish this situation?
You can use a TDS meter to test whether the TDS value increases, or even increases
significantly, before and after electrolysis. If there is a significant increase, the water electrolyzed by this cup is
basically not pure hydrogen molecules, and a large number of harmful molecules are predicted to enter the water.

You may wonder how there can be substances other than hydrogen in the water since it is hydrogen - oxygen
separated. When the platinum - catalyst coating on the membrane - electrode surface peels off, the
membrane - electrode can no longer achieve efficient hydrogen - oxygen separation. Therefore, some
unwanted by - products of electrolysis will surely enter the water.

 

Moreover, going back to the previous topic, membrane - electrode means hydrogen - oxygen separation,
but hydrogen - oxygen separation doesn't equal a good hydrogen - rich cup. Whether a hydrogen - rich cup
is good mainly depends on whether the membrane - electrode technology is qualified. Whether the
membrane - electrode technology is qualified mainly depends on the following aspects:
1. Duringlong - term electrolysis (for 1 - 2 years), there is no significant decrease in hydrogen concentration.
2. During long - term electrolysis (for 1 - 2 years), the voltage still doesn't increase, and the TDS doesn't increase
before and after electrolysis.
 

Main Technologies Advantages

Always keep in mind that only with good membrane - electrode technology can a hydrogen - rich water cup achieve
hydrogen production at a low voltage. Voltage is a key factor related to the water quality safety after electrolysis.
Once the voltage is high, even with hydrogen - oxygen separation, the risks of ozone, residual chlorine, and heavy
metals entering the water will increase.

 

Another point is that for some cups, the voltage is initially below the safe voltage of 2.5V. However, with the increase
in the number of hydrogen - generating times, reasons such as the peeling off of the catalytic coating of the membrane - electrode will cause the voltage to gradually rise. Then, some by - products of electrolyzed water will be generated,
such as ozone, residual chlorine, and heavy metals.

 

Suppose you use the cup 6 - 10 times a day on average. After one year of use, if you conduct various tests, you will
find that the TDS increases significantly, the hydrogen - generating concentration decreases significantly, and the
residual chlorine test fails.

Another point is that for some cups, the initial voltage is below the safe voltage of 2.5V. As the number of hydrogen - generating times increases, reasons such as the shedding of the catalytic coating of the membrane - electrode will cause the
voltage to rise gradually. Subsequently, by - products of electrolyzed water will be generated. But how can
we specifically distinguish this?

 

1. TDS test pen: You can try to use a TDS test pen to test the water cup after one year of use. If the TDS value increases significantly before and after electrolysis, it is obvious that this water cup is not good. It is highly likely that the catalyst of the membrane - electrode has fallen off, resulting in a significant increase in TDS.
2. Residual chlorine test paper: Observe the color change of the test paper to determine whether there is residual chlorine.
3. Hydrogen concentration: The hydrogen concentration will decrease significantly. You can use the same titration solution for comparative tests to observe the change in hydrogen concentration between the initial use and after 1 - 2 years of use.

 

For water cups with unqualified test results in various indicators caused by the continuous accumulation of hydrogen - generating times over time, we do not recommend their continued use. After all, drinking this water is for improving health. If you drink water containing ozone and residual chlorine, it will harm your health instead.

 

However, the water cups of CAHMTF use membrane - electrodes independently developed and produced by our own company. They have been applied in a 1 - kilowatt electric thruster. They have good long - term stability.
Based on strictly using pure water for hydrogen production, with 10 hydrogen - generating times per day and
each time lasting 5 minutes, there is no increase in TDS after 3 years of continuous use.
