A method of providing a cleaned gas diffusion layer for electrochemical applications includes providing a gas diffusion layer such that a first side of the gas diffusion layer is arranged on a first vacuum conveyor belt, cleaning an exposed second side of the gas diffusion layer, the second side being situated opposite the first side of the gas diffusion layer, transferring the partially cleaned gas diffusion layer to a second vacuum conveyor belt partially situated opposite the first vacuum conveyor belt, wherein the first vacuum conveyor belt and the second vacuum conveyor belt have a transfer region in which the gas diffusion layer is transferred from the first vacuum conveyor belt to the second vacuum conveyor belt such that the first side of the gas diffusion layer is exposed, and cleaning the first side of the gas diffusion layer.

The invention is directed to a barrier layer for corrosion protection in electrochemical devices, e.g. carbon based gas diffusion layers (GDLs) in electrochemical devices, comprising electrically conductive ceramic material and a non-ionomeric polymer binder. The electrically conductive ceramic material has an electrical conductivity of &#x3e;0.1 S/cm, preferably &#x3e;1 S/cm in air atmosphere (as detected by the powder method) and is selected from the group of precious metal and/or base metal containing oxides, carbides, nitrides, borides and mixtures and combinations thereof. Membrane-electrode assemblies (MEAs), catalyst-coated membranes (CCMs), gas diffusion electrodes (GDEs) and gas diffusion layers (GDLs) comprising the barrier layer of the invention show improved corrosion resistance, preferably against carbon corrosion; particularly in start-up/shut-down cycles and fuel starvation situations of PEM fuel cells.
