POROUS METAL BODY, METHOD FOR MANUFACTURING POROUS METAL BODY, AND FUEL CELL

摘要

An object of the present invention is to inexpensively provide a porous metal body which is usable for an electrode of a fuel cell or the like and which has excellent corrosion resistance. There is provided a porous metal body for a fuel cell, which is a sheet-shaped porous metal body, including at least nickel, tin, and chromium, in which the chromium concentration of at least one surface of the porous metal body is 3% to 50% by mass. In the porous metal body, preferably, the chromium concentration of one surface is higher than the chromium concentration of another surface.
