In some examples, solid oxide fuel cell system comprising a solid oxide fuel cell including an anode, an anode conductor layer, a cathode, a cathode conductor layer, and electrolyte, wherein the anode and the anode conductor layer each comprise nickel; and a sacrificial nickel source separate from that of the anode and anode conductor layer, wherein the sacrificial nickel source is configured to reduce the loss or migration of the nickel of the anode and/or the anode current collector in the fuel cell during operation.

Fuel cell system including sacrificial nickel source

A sealant composition for use in sealing solid oxide fuel cells is provided which comprises a glass component which comprises a mixture of alkali-free inorganic oxides, and an optional filler component dispersed in the glass component, said filler component being up to 40% by weight of the composition. The glass component can include, on a mole basis, 20 to 50% BaO, 1 to 10% YO, 5 to 20% BO, 10 to 30% SiO, 3 to 35% MgO, 2 to 20% CaO, 1 to 10% ZnO, and 0 to 5% ZrO, and exemplary filler components include zirconia, alumina, barium titanate, strontium titanate, and combinations thereof.
