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.


Product advantages:
PEM membrane electrode (directly coated with CCM) has high performance and strong stability.
We have developed membrane electrodes that combine the advantages of high performance and high stability. The most expensive raw materials for PEM water electrolysis membrane electrodes are catalysts, namely the noble metals iridium (Ir) and platinum (Pt). Generally speaking, the higher the hydrogen production of the electrolysis stack, the higher the operating current density, the higher the catalyst loading required, and the more stringent requirements for the structural strength of the catalytic layer, which greatly increases the difficulty and production cost of the membrane electrode.

By optimizing the formula of the catalyst slurry,
we adopt multi element gradient nanostructures to enhance the catalytic activity, increase the effective reactive area of the catalyst, and at the same time promote the charge transport and enhance the electrical conductivity
The catalyst slurry has high demands on the order of precious metal placement, premixing time, temperature, and dispersion process.
During the preparation of membrane electrodes, it is necessary to complete catalyst synthesis, slurry preparation, and CCM customized packaging professional machines, which can withstand the huge pressure of electrolytic stack assembly and the differential pressure of hydrogen and oxygen (> 30 barg) during operation. Effectively protect the membrane electrode to avoid problems such as mechanical damage and leakage.
