摘要： 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.

摘要： An electrode active material for capacitors contains a porous carbon material. The porous carbon material has a BET specific surface area of 800 m2/g or more. An X-ray diffraction image of the porous carbon material with CuKα rays has a peak Pk at 2θ=40° to 50°, and the peak Pk includes a component of a peak Pd111 attributed to a (111) plane of diamond crystals. When the X-ray diffraction image has a peak PG002 attributed to a (002) plane of graphite, a ratio of an intensity IG002 of PG002 to an intensity Ik of Pk (IG002/Ik) is 3.0 or less.
