Abstract
A seal is mountable in contact with two metal carriers of an electrochemical device, in particular a solid oxide fuel cell (SOFC) or a high-temperature solid oxide electrolyser cell (SOEC) for electrolysis of water vapour. This seal comprises a means for making the seal impermeable, comprising at least one vitreous material; and an electrically insulating supporting means that supports the impermeable means and that has two parallel main faces, an external peripheral edge and an internal peripheral edge, the seal being able to be mounted against these carriers via these main faces, which are covered with the impermeable means. The impermeable means partitions the supporting means between these internal and external edges while extending continuously from one of the main faces to the other through the supporting means, so that the impermeable means directly connects these carriers to each other.
