Title:
HYDROGEN/AIR SECONDARY CELL
Document Type and Number:
WIPO Patent Application WO/2012/035968
Kind Code:
A1
Abstract:
Provided is an air secondary cell having excellent durability and electrical charge/discharge cycle properties. A hydrogen/air secondary cell provided with: an air electrode which is arranged inside a cell container; a negative electrode which is arranged inside the cell container so as to face the air electrode, and which uses a hydrogen absorbing alloy; and an electrolyte retaining body which is arranged between the air electrode and the negative electrode and which retains electrolyte. The secondary cell has, inside the cell container, an electrolyte storage section which carries out the supply of electrolyte which decreases due to a charge reaction and carries out the storage of electrolyte which increases due to a discharge reaction, and at least part of the electrolyte retaining body is immersed in the electrolyte in the electrolyte storage section.
