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.
