Abstract
(EN)

According to one embodiment a solid oxide fuel cell device incorporates a seal resistant to hydrogen gas permeation at a in the range of 600° C. to 9000 C, the seal having a CTE in the 100×10−7/° C. to 120×10−7/° C., wherein the seal includes a sealing material that comprises in weight %, of: (i) 80 to 100 wt % of glass frit, wherein the glass frit includes in mole % MgO, 0-10% CaO, 0-30% BaO, 30-50% B2O3, 0-40% Al2O3, 10-30% SiO2, 10-30%; and (ii) a filler, 0 wt % to 20 wt %.
