The German submarine class 212 A is a highly advanced non-nuclear submarine design developed by Howaldtswerke-Deutsche Werft AG (HDW) for the German Navy. The propulsion system of U212A combines a conventional system consisting of a diesel generator set with a lead acid battery. In addition to this it has an Air-Independent Propulsion (AIP) system, which is used for low speed silent cruising, with fuel cells using oxygen and hydrogen as reactants. U212A has been developed for use of an extremely silent fuel cell plant that runs on a set of nine 34-kilowatts Siemens polymer electrolyte membrane (PEM) hydrogen fuel cells. Oxygen is stored in liquid form (LOX) in tanks, hydrogen is stored in gaseous state in metal hydride tubes both outside the pressure hull.
