AEM Water Electrolyzer is divided into cathode and anode chambers, with the core configuration being the MEA. The MEA achieves zero-gap ion transport by pressing together the GDL, catalyst layer, and anion exchange membrane. The anion exchange membrane is the core component of AEM technology, with the main functions of conducting hydroxide ions (OH⁻) while preventing direct transfer of gas and electrons between electrodes.

Characteristic:

1. MEA needs to be produced by hot pressing. Hot pressing can significantly improve the interfacial contact between the electrode and the membrane, reduce contact resistance, and enhance performance and long-term stability.Research shows that to achieve the ideal hot-pressing effect, the hot-pressing temperature should be set between 150-250°C, the pressure between 0.5 MPa and 2.5 MPa, and the time between 2-10 minutes. Hot-pressing parameters need to be optimized based on the specific ion membrane material and electrode structure, and it is recommended to conduct parameter screening experiments before formal testing.

2. AEM electrolysis water testing also requires heating. Research shows that 60-80°is the ideal temperature condition. Users need to prepare Φ6mm heating rods (heating plates) and Φ2mm thermocouple.

3. Nickel plated with gold can further enhance corrosion resistance. In addition, gold has excellent electrical conductivity, which can further reduce the contact resistance between the electrode plate and adjacent components.

Parameter:

1.The electrode plate can be used as an end plate, a channel plate and a current collector, which can be quickly assembled and disassembled, and is easy to clean.

2.The base plate is 99.9% nickel, with an outer layer of gold plating.

3.The channel shape is serpentine S channel by default, and it supports customized parallel, cross-finger, dot matrix, multi-S channel, etc.

4.The channel width and depth are 1.5mm by default, and support customized 0.5mm, 1mm, 2mm, etc.

5.The area includes 1cm2, 4cm2, 5cm2, 9cm2, 16cm2, 25cm2, 50cm2, 100cm2, etc.

6.There are two kinds of gaskets: PTFE gasket and fluorine gasket. It is important that the user informs the name and thickness of the electrode material to be used in order to equip it with a suitable gasket.
