Abstract (en)
[origin: WO2020020467A1] The invention relates to a method for producing a porous transport layer (4) for an electrochemical cell, said method consisting of mixing a metal powder with a binder and subsequently forming same into a foil. The foil is laid on a porous metal layer (8), the binder is then removed, and the remaining brown sublayer (9) is sintered to the porous metal layer (8), producing a porous transport layer (4) which has a porous metal layer (8) with a microporous metal layer (9) applied thereon.
