Application of Nickel Foam on AEM Hydrogen Generation Electrolyzer

In the AEM hydrogen reaction, nickel foamis used as the Material for the porous transport layer (PTL) in the electrolyzer, which affects the efficiency and stability of the overall electrolysis system.
Nickel acts as a good electrical conductor to ensure the transfer of electrons through the pores in the reaction environment. The three-dimensional structure of nickel Foam provides good support for the reaction environment and helps to maintain the stability and structural strength of the electrode. At the same time, the porous structure of nickel foam provides a large active surface area, thereby increasing the reaction rate.

Function
High conductivity
Nickel is a good conductor of electricity, and the three-dimensional structure of Nickel Foam provides a high surface area, which contributes to the distribution of electric current.

Catalyst
Nickel foams are usually coated with a catalyst such as nickel or other suitable catalysts. These catalysts help to catalyze the water electrolysis reaction, which breaks down water into hydrogen and oxygen. The foam structure provides a high surface area that promotes catalyst distribution and reaction efficiency.

Support Structure
The three-dimensional structure of nickel foam provides excellent support, helping to maintain the stability and structural strength of the electrode to ensure long-term operation.

Ion Transport
In alkaline environments, Nickel Foam allows the transport of hydroxide ions (OH-), which facilitates water electrolysis.

Improved electrode activity
The porous structure of nickel foam greatly enhances the reaction area, increasing the reaction rate and improving efficiency.

Lightweight
Nickel foam structures are generally lighter than solid materials, which helps to reduce the total weight of the structure.

Applications
Nickel foam has many functions such as damping, vibration damping, noise reduction, flame retardant, filtration and electromagnetic shielding. It plays a role in electrochemical engineering, chemical engineering, automobile, petroleum and other fields.
