Description

CMI manufactures porous metal gas diffusion layers which are widely used in high performance electrolyzer and fuel cell applications. 
Our porous metal gas diffusion layers are manufactured from isostatic cool pressing and high temperature vacuum sintering. There is broad selection of corrosion resistant material to be used to support all operation temperatures. It can also be coated with surface treatments or catalyst layers to enhance performance. Controllable porosity is provided to give the best balance of gas diffusion and water transport. 

Features

－Even distribution of gas flow     
－Low thickness variation 
－Ultra-thin down to 0.25mm
－Ductile and machinable 
－High strength for high DP applications
－Good corrosion resistance
－Maintain uniform porosity under high   compressive loads
