A hollow body composed of an electrically conducting material and extending longitudinally along an axis is connected at one axial end to a connection element composed of an electrically conducting material and extending along the axis. A first thread is provided on the hollow body at the one axial end running about the axis, while a second thread is provided on the connection element running about the axis, so that the second thread is mechanically supported by the first thread. An insulation-material extent between the first thread and the second thread electrically isolates the hollow body from the connection element.

The superconducting current-limiting device contains at least one coil (), the conductive track of which is formed from at least one band-shaped superconductor (), where a holding element () is located between adjacent coil windings. The holding element () is constructed wider than the superconductor () in the axial direction of the coil (). The holding element () further includes a flat strip () and an undulating strip (). The flat strip () extends essentially parallel to the band-shaped superconductor () at an essentially constant distance () therefrom. The undulating strip () extends essentially parallel to the flat strip (), and in the longitudinal direction periodically has regions () distant from and regions () close to the flat strip (). The regions () of the undulating strip () near to the flat strip have a mechanical connection () to the flat strip (). The regions () of the undulating strip far from the flat strip have recesses () of such a kind that an at least approximately close-fitting mounting of the band-shaped superconductor () relative to the flat strip () is facilitated.

A method for dissolving a hardened glass solder, a method for separating components joined by a glass solder, a method for disassembling a fuel cell, and an apparatus for disassembling a fuel cell, include heating the hardened glass solder in a melt of a hydroxide. As a result, components which had been joined through the use of the hardened glass solder are able to be reused or subjected to a recycling process.
