First claim
Opening claim text (preview).
1 . A chromium adsorption material comprising: a porous body made of a metal material; and a chromium adsorbent carried inside pores of the porous body, wherein the metal material includes a first metal and a second metal, the first metal includes nickel, and the second metal includes at least one selected from the group consisting of tin, aluminum, cobalt, titanium, manganese, tungsten, copper, silver, and gold. 2 . The chromium adsorption material according to claim 1 , wherein the metal material includes an alloy of the first metal and the second metal. 3 . The chromium adsorption material according to claim 1 , wherein the second metal is tin. 4 . The chromium adsorption material according to claim 1 , wherein the porous body has a skeleton with a three-dimensional network structure. 5 . The chromium adsorption material according to claim 1 , wherein the porous body has a porosity of 70 to 98%. 6 . A fuel cell comprising: a cell structure body; a first supply flow path; and a second supply flow path, wherein the cell structure body includes a cathode, an anode, and a solid electrolyte layer interposed between the cathode and the anode, an oxidant to be supplied to the cathode passes through the first supply flow path, a fuel to be supplied to the anode passes through the second supply flow path, and the chromium adsorption material according to claim 1 is arranged in the first supply flow path.
