Description
16cm² surface area is ideal for electrochemical hydrogen compression experiments when testing new types of catalyst or membranes. With 16cm² the compression current should be sufficient to compress up to 100bar in under 10 minutes (given the cathode volume is limited to 5cm³). Upon a positive result, usually a larger area test (40cm² or larger) will be initiated and further on upscaled for commercial use.
PEM components offers a 16cm² Gas Diffusion Electrode (GDE). Its dimensions are 40mm by 40mm to fit in Proton Technologies 16cm² EHC single cell. The surface is coated with a Pt/C (50%wtPt) catalyst onto SGL Sigracet 28BC gas diffusion layer (GDL). It is mainly used as electrodes for fuel cells, cathodes of electrolyzers, compression or purification cells. Some standard loadings are offered. Lower loadings are often used as anodes of fuel cells, cathodes for electrolyzers, compression or cathode for purifyers. Higher loadings are mainly used for cathodes of fuel cells or anodes for purification.
Apart from these standard electrodes, PEM components also offers tailored solutions. It has all production equipment in house as well as the required expertise therefore, it is possible to specify your desired loading, to incooperate your own catalyst material or even to switch out GDL to your preferred GDL. Please contact us for the possibilities to tailor make your GDE’s

How to use
Please use powder free nitril gloves when handling electrodes to prevent potential contamination. Avoid contact with volatile materials or enriched oxygen atmosfears without proper safety precautions.rnrnThere are 2 sides on the GDE, namely:rnu003culu003ern tu003cliu003eThe grey-ish fibre sideu003c/liu003ern tu003cliu003eThe black smooth sideu003c/liu003ernu003c/ulu003ernThe black smooth side should face the membrane as it is the catalyst coated side.rnrnThe electrodes are 235 micrometer thick and can be compressed to enhance contact. PEM components provides these spacers in the form of border material.
