Abstract
Official abstract text for this publication.
A plate-like porous metal body having a three-dimensional mesh-like structure and containing nickel (Ni). The content of the nickel in the porous metal body is 50% by mass or more. The porous metal body has a thickness of 0.10 mm or more and 0.50 mm or less.
First claim
Opening claim text (preview).
1 . A plate-like porous metal body having a three-dimensional mesh-like structure, the porous metal body comprising nickel (Ni), the content of the nickel in the porous metal body being 50% by mass or more, the porous metal body having a thickness of 0.10 mm or more and 0.50 mm or less. 2 . The porous metal body according to claim 1 , the porous metal body having a porosity of 55% or more and 85% or less. 3 . The porous metal body according to claim 1 , the porous metal body further comprising chromium (Cr), the content of the chromium in the porous metal body being 1% by mass or more and 50% by mass or less. 4 . A fuel cell comprising the porous metal body according to claim 1 , the porous metal body serving as a gas diffusion layer. 5 . A method for producing a plate-like porous metal body having a three-dimensional mesh-like structure, the porous metal body containing nickel (Ni), the method comprising: a step in which an electrical conduction material containing a carbon powder is applied onto a surface of a skeleton of a plate-like resin shaped body having a three-dimensional mesh-like structure in order to make the surface of the skeleton of the resin shaped body conductive; a step in which a nickel-coating layer is deposited on the resin shaped body such that the content of the nickel in the porous metal body is 50% by mass or more so as to form a resin structure; a step in which the resin shaped body is removed from the resin structure in order to prepare a porous metal body; and a step in which the porous metal body is rolled to a thickness of 0.10 mm or more and 0.50 mm or less. 6 . The method for producing a porous metal body according to claim 5 , wherein the carbon powder is a powder of carbon black, active carbon, or graphite.
