A lanthanoid silicide-coated silicon carbide material whereof the surface is coated with a silicide, this silicide being a reaction product of an oxide of a lanthanoid rare earth element or yttrium with silicon carbide, or a reaction product of a compound oxide of a lanthanoid rare earth element or yttrium and silicon with silicon carbide; and a lanthanoid silicide-coated silicon carbide as above whereof the surface is further coated with an oxide of a lanthanoid rare earth element or yttrium, or with a compound oxide of a lanthanoid rare earth element or yttrium and silicon.

A solid electrolyte fuel cell with various improved features has been described. The cell comprises many unit cells each having a structure in which there are laminated a gas-permeable oxygen electrode made from an electron-conducting material, a solid electrolyte consisting of a (CeO.sub.2).sub.1-x (CaO).sub.x (x=0.05 to 0.8) binary system or a third component-containing (CeO.sub.2).sub.1-x (CaO).sub.x (x=0.05 to 0.8) system and a gas-permeable fuel electrode made from an electron-conducting material on a gas-permeable support, many unit cells being connected to each other in series with interconnectors by subjecting end portions of the electrolytes to a masking treatment or the like.

A method of welding for hard surfacing comprises feeding a powdery mixture, prepared by adding at least one of the powders on NbC, VC, and TiC to the powder of an alloy steel containing either Fe, Ni, and Cr, or Fe and Cr as the chief components, to an arc produced between a base metal of iron or steel and a nonconsumable electrode shielded by an inert gas, and thereby forming a weld metal on the base metal.
