Glass composition for use as sealing material in fuel cells, comprising a glass matrix with main components consisting of SiO , Al O , and one or more compounds from group I metal oxides and/or group II metal oxides, and a filler material evenly dispersed in the matrix, wherein the filler material consists of particles of one or more refractive compounds from the group: MgO&mdash;MgAl O , stabilized zirconia, rare earth oxides, (Mg,Ca)SiO , Mg SiO , MgSiO , CaSiO , CaZrO , ThO , TiO , M AlSi O , where M &equals;Ca, Sr or Ba.

High temperature sealing material

A supported superconductor device which is useful as a superconducting current lead or as a high voltage current regulator. The device is formed of a tubular support, with a layer of ceramic, glassy or glass ceramic material adhered to the inner wall of the tubular support, the layer of material embedding a superconducting layer centrally arranged within the material of the first layer, the material of the first layer having a minimum expansion coefficient and being reinforced with pore filling material.
