A liquid fuel cell comprising a plurality of unit fuel cells each having a positive electrode () for reducing oxygen, a negative electrode () for oxidizing liquid fuel, and an electrolyte layer () interposed between the positive electrode () and the negative electrode (), and a section () for storing liquid fuel (), wherein power can be generated stably while reducing the size by arranging the plurality of unit fuel cells on the substantially same plane. Each electrolyte layer of the unit fuel cell preferably constitutes a continuous integrated electrolyte layer.

Liquid fuel cell with a planer electrolyte layer

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.
