Pem Catalyst Coated Membranes

How does CCM work?

     CCMs typically consist of structurally precise catalysts of platinum (cathode) and iridium (anode) applied in a maximized manner for solid membrane hydrogen production.

Water flows into the CCM, where an iridium catalyst uses electrical energy to break down water molecules into oxygen, protons, and electrons. 

      Electrons are driven through an external circuit and protons then pass through the membrane. The platinum catalyst brings the protons and electrons back together to form hydrogen.

Overcome the technical problems of large-size PEM membrane electrode for electrolysis water electrolysis, improve the stability and mechanical strength of the membrane electrode, and reduce the difficulty of stacking

Whatever your PEM membrane electrode needs, we can create the right customized solution for you. And with our market-leading PEM technology, which produces the purest green hydrogen on the market.

     The innovative technology CCM is the core of the PEM electrolyzer, which promotes the electrochemical reaction and makes the hydrogen to be produced through the ultrasonic spraying process to make the CCM membrane electrode, and the PEM electrolyzes the water to produce the hydrogen membrane electrode. The membrane electrode product has good consistency and strong tolerance

CCM-optimized systems are designed to meet customer requirements using tailor-made formulations and commercial-scale manufacturing processes.

Catalyst Coatings Development

By optimising the catalyst slurry formulation, slurry dispersion and spraying process, the catalyst particles are better encapsulated, and the efficient proton transport improves the catalyst utilisation and enhances the gas transport performance.The multi-layer structure improves the contact area between the catalyst and the reactants, thus increasing the activity of the catalyst with high power density, high efficiency and high durability. In addition, the new CCM protects the catalyst from corrosion in the electrolyte, thus improving the stability of the catalyst.

The system advantage of ultrasonic catalyst coating is the highly uniform and durable coating technology with a very high precious metal utilisation rate (90%). Unique catalyst paste structure "adhesion" coating is very durable and prevents cracking or flaking of the catalyst layer. Uniform and consistent catalyst layer for improved electrochemical performance

 

Membrane Electrode Encapsulation

Runner cutting: High-precision cutting equipment prevents deformation of the membrane electrode; it can make the membrane electrode assembly and the encapsulation mould tightly bonded, and improve the hermeticity of the membrane electrode. It can make the gas diffusion layer in the membrane electrode assembly and the sealing border firmly fixed to prevent gas leakage. It can improve the durability of the membrane electrode, which can withstand the pressure of the electrolysis stack assembly as well as the differential pressure operation of hydrogen and oxygen. The encapsulation process of the membrane electrode is the key to the performance and reliability of electrolysis tanks.

High-strength Porous Diffusion Layer

Improved gas transfer efficiency. The size and porosity of the porous structure are optimised to ensure fast and uniform gas transfer in the PTL; improving power density and efficiency

Can withstand the pressure and stress generated during the operation of the electrolyser with good strength and durability; effectively improving the performance, cost and reliability of the electrolyser.

Customizable

The MEAs can be tailored with respect to stack size, stack design and operating conditions according to specific customer needs.

This will allow our customers to shorten the time it takes to bring their products to market. 

Long-term testing and validation of CCM membrane electrode catalysts

We have done a lot of experiments and data comparisons on the performance, monitoring and product data of PEM electrolyser, 

and all the indexes are ahead of the performance of the existing electrolyser in China, 

and we have a wealth of practical experience in the process applied to the overall structure of PEM electrolyser.

Electrolysis hydrogen production summarises the mutual conversion of wind power, photovoltaic and other green energy sources,

making use of the earth's most abundant resource - "hydrogen", without any polluting emissions in the production process,

hydrogen combustion ratio is higher than common energy storage material, no doubt green hydrogen is the most ideal energy source.

Catalyst-sprayed membrane electrode technology for PEM electrolysis drives the scale and efficiency of today's electrolyser

Green hydrogen for decarbonisation is produced by electrolysis using renewable electricity and water and producing only hydrogen and oxygen. 

It is very effective, which can help decarbonise many different industries, whether it is used as an alternative energy carrier, for large -scale long -term energy storage.
