摘要： A porous body includes a framework having a three-dimensional network structure, the framework having a body including crystal grains including nickel and cobalt as constituent elements, the cobalt having a proportion in mass of 0.2 or more and 0.8 or less with respect to a total mass of the nickel and the cobalt, the crystal grains having a shorter grain diameter of 2 μm or more, as determined in a first observed image obtained by observing the body of the framework in cross section at a magnification of 200 times.

摘要： A cord-rubber composite includes one or more steel cords each including a steel wire, and rubber covering at least a part of a surface of each of the one or more steel cords. The one or more steel cords each include the steel wire and a metal nanoparticle layer stacked on a surface of the steel wire. The metal nanoparticle layer contains a first metal nanoparticle and a second metal nanoparticle. The first metal nanoparticle contains copper. The second metal nanoparticle contains one or two or more selected from zinc, cobalt, tin, iron, nickel, aluminum, and oxides thereof.

摘要： A proton-conductive solid electrolyte member has an electrolyte layer and an anode layer. The electrolyte layer contains a metal oxide having a perovskite crystal structure. The anode layer contains Fe2O3 and the metal oxide. The metal oxide is a metal oxide expressed by the following formula [1], or a mixture or a solid solution of a metal oxide expressed by the following formula [1]: AaBbMcO3-δ, where A denotes one element selected from the group consisting of Ba and Ca; B denotes one element selected from the group consisting of Ce and Zr; M denotes one element selected from the group consisting of Y, Yb, Er, Ho, Tm, Gd, In, and Sc; a is a number satisfying 0.85≤a≤1; b is a number satisfying 0.50≤b≤1; c is a number satisfying c=1−b; and δ is an oxygen deficiency amount.
