Abstract:
Method for the manufacture of a hydrogen-permeable membrane having a thickness of not greater than 30 μm. The method includes plasma spraying at least one dense layer on a porous substrate such that during the plasma spraying, one sweep of a process beam deposits material particles over the substrate in a form of individual splats which do not produce a cohesive layer and said material particles include a proton-conducting ceramic material and an electron-conducting metallic component. The plasma spraying is LPPS-TF that utilizes a spraying distance of between 200 mm and 2000 mm, a sprayable powder starting material having a particle size range between 1 and 80 μm and containing the proton-conducting ceramic material and the electron-conducting metallic component and a process beam dispersing the sprayable powder starting material to a cloud.

Claim (Index 11):
A method for the manufacture of a hydrogen-permeable membrane having a hydrogen flow rate greater than 10 milliliter per minute and square centimeter, comprising:\n plasma spraying at least one dense layer on a porous substrate, said at least one layer comprising a proton-conducting ceramic material and an electron-conducting metallic component, wherein the proton-conducting ceramic material is an oxide of the perovskite type, wherein the at least one layer:\n is deposited by sweeping a plasma beam over the substrate such that one sweep of the plasma beam forms individual splats over the substrate; and \n includes therein migration paths and trickle paths that increase electron conductivity of the at least one layer and contain the electron-conducting metallic component, and \n wherein the plasma spraying is a low pressure plasma spraying thin film (LPPS-TF) process and the plasma spraying utilizes:\n a sprayable starting material having a particle size of between 1 \u03bcm and 80 \u03bcm; and \n a spraying distance defined between an outlet nozzle and the substrate that is between 200 mm and 2000 mm.
