Abstract:
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.
Abstract:
An electrolyte layer-anode composite member for a fuel cell includes a solid electrolyte layer containing an ionically conductive metal oxide M1, a first anode layer containing an ionically conductive metal oxide M2 and nickel oxide, and a second anode layer interposed between the solid electrolyte layer and the first anode layer and containing an ionically conductive metal oxide M3 and nickel oxide. A volume content Cn1 of the nickel oxide in the first anode layer and a volume content Cn2 of the nickel oxide in the second anode layer satisfy the relation Cn1
Abstract:
An object of the present invention is to provide, at a low cost, a porous metal body that can be used in an electrode of a fuel cell and that has better corrosion resistance. The porous metal body has a three-dimensional mesh-like structure and contains nickel (Ni), tin (Sn), and chromium (Cr). A content ratio of the tin is 10% by mass or more and 25% by mass or less, and a content ratio of the chromium is 1% by mass or more and 10% by mass or less. On a cross section of a skeleton of the porous metal body, the porous metal body contains a solid solution phase of chromium, nickel, and tin. The solid solution phase contains a solid solution phase of chromium and trinickel tin (Ni3Sn), the solid solution phase having a chromium content ratio of 2% by mass or less, and does not contain a solid solution phase that is other than a solid solution phase of chromium and trinickel tin (Ni3Sn) and that has a chromium content ratio of less than 1.5% by mass.
