AEMWE Crosslinked PtRu/C Cathode GDE

This product is a variant of the crosslinked Pt/C cathode GDE (SKU:1001003). Testing shows that PtRu/C catalyst performs better than Pt/C for hydrogen evolution reaction (HER) in AEM water electrolysis without noticeable difference in durability within the test time window. This crosslinked PtRu/C cathode GDE may offer a better option for AEMWE applications. 

This cathode gas diffusion electrode (GDE) consists of 60% PtRu/C catalyst mixed with an anion exchange ionomer, and coated on a carbon paper. It is a crosslinked cathode electrode using a proprietary technology designed for anion exchange membrane (AEM) electrolysis or other related electrochemical applications. One of the big challenges facing AEM electrolysis is the detachment of catalyst from anion exchange ionomer, causing very high degradation rate. This PtRu/C cathode GDE has been crosslinked just to deal with this problem. The crosslinked cathode provides amazing durability in addition to the expected performance from PtRu/C catalyst, which is enabling the rapid commercialization of AEM electrolyzers.

It can also be used in anion exchange membrane fuel cell as either anode GDE or cathode GDE.

Handling

• Handle the product in a clean, dry, low-dust environment.
• Wear clean disposable nitrile gloves during handling.
• Avoid direct contact with the catalyst/active surface to prevent contamination from oils, sweat, salts, etc.
• Do not fold, bend, scratch, or rub the electrode to avoid mechanical damage to the active layer.
• Recommended storage: cool, dry, and protected from light, away from heat sources and corrosive vapors.
