Ion exchange membrane (AEM) water electrolysis for hydrogen production AEM is somewhat a hybrid of PEM and traditional separator-based alkaline electrolysis. AEM electrolyzer principle: At the cathode, water is reduced to produce hydrogen and OH–. OH– flows through the separator toward the anode, where it recombines at the anode surface to produce oxygen. Research shows that at 85°C, the current density at 1.8V voltage is 2.7A/cm2. When NiFe [...]

AEM Electrolyte AEM Electrolytes play an important role in improving the electrolysis efficiency of AEM. Commonly used electrolytes in AEMWE are KOH, K2CO3 and pure water. Different from the high-concentration alkaline electrolyte used in traditional ALK, since the anion exchange membrane can conduct OH−, AEM can use low-concentration alkaline solution, which can avoid safety problems caused by highly corrosive electrolytes during the experiment, not only reducing the cost [...]

AEM Water Electrolysis Catalyst Layer Preparation Process The fabrication of catalyst layers (CL) covers a variety of technical means, such as catalyst spraying (whether in slurry form or other forms), electrodeposition (electroplating, abbreviated ED), thermal decomposition, and screen printing. An ideal catalyst layer should have a large pore surface area to effectively transport reactants and products between multiple active sites of the electrode. Similar to other parts of [...]
