Abstract: The invention relates to an implant made of biocompatible materials, in particular a prosthesis implanted without cement for traumatology and/or orthopedics, which has a main body with an anchoring region which anchors in bone or tissue, with the anchoring region being provided at least partially with a covering layer, the covering layer being formed from a powder using a thermal spraying method, in particular a plasma spraying method. The powder consists essentially of calcium phosphate and comprises antibacterially effective active constituents.

Abstract: Avoiding the use of porous ceramic bearing structures, the proposal is for a 3-layer electrolyte fuel cell element, one electrode (1) of which is at the same time the bearer plate for the active cell element (12, 2, 3), is integrated via component (4) into the frame structure for a cell battery made up of individual elements, and in which the mechanical closing force between the frame structure and the active cell element is released with the aid of a spring-loaded region (11), in order not to expose the thin electrolyte layer (2) to thermally induced mechanical stresses. The active cell element, a combination of two porous and metallic electrodes (1, 3) with a gastight oxide electrolyte layer (2), are preferably produced by the vacuum plasma spray process.
