<P>PROBLEM TO BE SOLVED: To provide a corrosion-resistant metallic clad material for a separator, which is superior in corrosion resistance and workability, and to provide a manufacturing method therefor. <P>SOLUTION: This metallic clad material comprises a core material 21 made of a ferritic stainless alloy containing 11-20% chromium, and a cladding layer 22 of titanium or a titanium alloy, which covers one side or both sides of the core material 21. The constitution enables the core material to be annealed at a comparatively low temperature, inhibits the formation of an intermetallic compound therein to the minimum, can minimize the formation of cracks in the cladding layer even when the metallic clad material is pressed to form a passage, because of having improved formability, and enables the metallic clad material to form a deep channel. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
