The present invention provides a novel anion conductor which comprises a layered metal hydroxide and can be used as an alkaline electrolyte film for use in a fuel cell or the like. An anion conductor characterized by comprising a molded product of a layered metal hydroxide represented by formula (1): [M.sub.x(OH).sub.y(A).sub.(αx-y)/z-nH.sub.2O] (wherein M represents a metal that can serve as a bivalent or trivalent cation; α represents the number of valency of the metal M, A represents an atom or an atomic group that can serve as an anion, and z represents the number of valency of the anion A, wherein, when (αx-y)/z is 2 or greater, A's may be different types of anions which can serve as anions having the same valencies as each other, or may be anions having different valencies from each other; and n represents the average number of molecules of interlayer water contained per one repeating unit). The anion conductor according to the present invention is composed of an inorganic material, and therefore has excellent heat resistance and physical strength and can be operated for a longer period at a higher temperature compared with the conventional ones when used as an anion conductor for a fuel cell, an air cell or the like.

Humidity and temperature may impact the physical properties of Basic Copper Nitrate (BCN), (Cu.sub.2(OH).sub.3(NO.sub.3), BCN) inorganic particles. The use of hydrophobic surface coatings on these inorganic particles have been found to protect and/or minimize the amount of surface degradation over a period of time.
