The method for manufacturing a hydrogen permeation barrier comprises the steps of a) depositing on a substrate (SUB) a layer system (LS) comprising at least one layer (L1,L2,L3); characterized in that step a) comprises the step of b) depositing at least one hydrogen barrier layer (HPBL) comprising an at least ternary oxide. The apparatus comprises a sealable volume and a wall forming at least a portion of a boundary limiting said volume, wherein said wall comprises a hydrogen permeation barrier comprising a layer system (LS) comprising at least one layer, wherein said layer system comprises at least one hydrogen barrier layer (HPBL) comprising an at least ternary oxide. Preferably, said at least ternary oxide is substantially composed of Al, Cr and O, and said depositing said at least one hydrogen barrier layer (HPBL) is carried out using a physical vapor deposition method, in particular a cathodic arc evaporation method. Preferably, step a) comprises depositing on said substrate at least one of: an adhesion layer (AdhL), a hydrogen storage layer (HStL), a protective layer (ProtL), in particular a thermal barrier layer (ThBL), a diffusion barrier layer (DBL), an oxidation barrier layer (OxBL), a chemical barrier layer (ChBL), a wear resistance layer (WRL). Excellent hydrogen permeation barrier properties can be achieved, and the layer system can be tailored as required by an envisaged application.
