MeliDiff® is a specially developed metallic expanded metal laminate for use in PEM or alkaline electrolysis systems.
The purely metallic MeliDiff® gas diffusion layers and the proton-conducting membrane (PEM) are the main compoment of the PEM water electrolysis. The MeliDiff® conducts electricity and water to the membrane and leads the forming gases H2 and O2 simultaneously.
The connection of different expanded metals is carried out by a specially developed welding process. The different layers of expanded metal are welded at all points of contact, resulting in a full-surface welded connection.
The MeliDiff® gas diffusion layer are characterised by:
MeliCon invented a unique welding procedure which offers the posibility to vary the numbers of mesh layers and the mesh sizes to meet the technical requirements.
This all means that the customer recieves GDL components that can be adapted right to his needs, including the geometric conditions which can be fulfiled very precisely by laser cutting, up to dimensions of 1000 x 1000 mm.
