ABSTRACT:
A lighter-than-air ship using hydrogen or other gas as a lift gas with at least one hydrogen fuel cell aboard. The fuel cell can draw hydrogen fuel from the lift gas reservoir to produce electricity both for the ship's use and optionally for propulsion. The waste product of the fuel cell is water which can be used for the needs of a crew on the ship. The hydrogen lift gas chamber, which can be compartmentalized for lift control, can be surrounded by a safety jacket filled with an inert gas and contain optional hydrogen and/or oxygen sensors.
