Sealed type hydrogen-oxygen secondary battery

Abstract

Abstract PURPOSE:To make a battery compact and make possible high rate charge and discharge by accommodating each component, oxygen, and hydrogen within a battery and sealing it. CONSTITUTION:A positive electrode 1 and negative electrode 2 comprising gas diffusion electrodes, an ion exchange resin film 3 are bonded together with a hot press. Water is poured in a battery from a water supply hole 7 of a battery frame 6, then the water supply hole 7 is sealed. When the battery is charged, oxygen gas evolves from the positive electrode 1 and pressure in an oxygen chamber 8 is increased with progress of charging. Hydrogen evolves from the negative electrode 2, and pressure in a hydrogen chamber 9 is increased. When the battery is discharged, oxygen in the oxygen chamber 8 and hydrogen in the hydrogen chamber 9 react. This sealed type secondary battery can be quickly charged at high current density and discharged at high current density.
