25cm² surface area is the next step for evaluation experiments of new types of catalyst or membranes. It is typically used within academia or R&D labs as a mean for small scale testing of newly made materials. Upon a positive result, usually a commercial size test is initiated.
PEM components offers a 25cm² Gas Diffusion Electrode (GDE). Its dimensions are 50mm by 50mm and the surface is coated with a Pt/C (50%wtPt) catalyst onto SGL Sigracet 28BC gas diffusion layer (GDL). Its dimensions are designed for PEM components 25cm² test cell, but also fit other It is mainly used for as electrodes for fuel cells, cathodes of electrolyzers, compression or purification. Some standard loadings are offered, lower loadings are often used for anodes of fuel cells, cathodes for electrolyzers, compression or cathode for purifyers. Higher loadings are 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

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.
