MEA(CCM) Technology

Catalyst layer structure, coating quality and membrane-electrode bonding quality directly affect hydrogen production efficiency, cell voltage characteristics and long-term operating stability in PEM water electrolysis. CS Hydrogen develops its MEA (CCM) technology on the basis of in-house manufacturing processes.

From Catalyst Ink to Finished CCM

MEA (CCM) is the catalyst coated membrane that determines the performance and durability of PEM water electrolysis.

From catalyst ink preparation to finished CCM, CS Hydrogen delivers uniform quality and stable performance through its own manufacturing process.

Catalyst ink preparation
STEP 01 Catalyst Ink Preparation Catalyst Ink Preparation

Catalyst, solvent and ionomer are combined to prepare catalyst ink for PEM water electrolysis.

Ultrasonic dispersion
STEP 02 Ultrasonic Dispersion Ultrasonic Dispersion

The ink is treated so that catalyst particles and ionomer disperse uniformly.

Ultrasonic spray coating
STEP 03 Ultrasonic Spray Coating Ultrasonic Spray Coating

An ultrasonic spray coating process is applied to form a uniform catalyst layer.

Hot press and decal transfer
STEP 04 Hot Press / Decal Transfer Hot Press and Decal Transfer

The electrode and membrane are aligned, then bonded using heat and pressure.

CCM finishing
STEP 05 CCM Finishing CCM Finishing

The protective film is removed and bonding is inspected to verify final quality.
