Abstract
A metal oxide-hydrogen battery having an outer safety shell. The battery to be used in a confined area such as in an aircraft or manned spacecraft, and includes a pressure vessel that contains at least one cell module. Hydrogen gas under pressure is confined within the pressure vessel and is impregnated in the cell modules. An outer shell, preferably formed of molded plastic, is disposed around the pressure vessel and a vent conduit connects the space between the vessel and the shell with the exterior. Any hydrogen that accidentally leaks from the vessel is captured in the space and vented to the exterior.
