PtX-CSMEA
This is an integrated 3-layer or 5-layer Membrane Electrode Assembly(MEA) with a gas diffusion layer (GDL) for hydrogen/air (oxygen) fuel cells.
The standard MEA features a platinum loading of 0.025–0.2 mg/cm2, a 50.8-µm membrane, and a 280-µm carbon paper GDL.
Custom sizes and configurations are available with no minimum order quantity, and this hydrogen/air (oxygen) MEA is manufactured in a 5-layer structure.
