Abstract
An air-hydrogen battery with high energy density and satisfactory cycle characteristics is provided. The air-hydrogen battery includes: a positive electrode made of an air electrode; a negative electrode provided with a hydrogen-absorbing alloy; and a cation-exchange film or an anion-exchange film formed as an electrolyte between the positive electrode and the negative electrode, wherein a periphery of the hydrogen-absorbing alloy of the negative electrode is covered with an anion-exchange resin, whereby the contact area between the anion-exchange resin that functions as an electrolyte and the hydrogen-absorbing alloy is increased, and the utilization factor and resistance to corrosion of the hydrogen-absorbing alloy are enhanced.
