Popis: | Hydrogen separation membranes are typically composed of three components: the porous support (ceramic or metallic, as studied in the present work), the porous ceramic interface layer and the hydrogen selective dense layer (usually Pd or a Pd based alloy). The development of a good support and an appropriate ceramic interface layer is a key issue in the high performance membrane manufacturing process. Metallic supports specifically developed for this application have yet to be developed; those used have different features and are manufactured for applications such as filtering devices. There is a clear need to develop porous supports for hydrogen separation membranes that have good surface quality (roughness and pore size) to allow the deposition of a thin selective layer (typically of Pd). In addition, the development of the ceramic layer is of importance, to allow the deposition of a Pd continuous layer of minimum thickness to increase hydrogen permeation and decrease manufacturing costs by minimising us... |
