Abstract A FUEL CELL SYSTEM FOR AN UNDERWATER VEHICLE HAVING AT LEAST ONE FUEL CELL MODULE FOR SUPPLYING ELECTRICAL POWER FOR SAID VEHICLE. A FIRST TANK CONTAINING HYDROGEN IS CONNECTED TO ONE REACTANT CHAMBER OF A FUEL CELL MODULE AND A SECOND TANK CONTAINING OXYGEN IS CONNECTED TO ANOTHER REACTANT CHAMBER OF THE FUEL CELL MODULE. THE HYDROGENPRODUCT WATER OUTPUT FROM THE HYDROGEN REACTANT CHAMBER IS CONDENSED AND SEPARATED AND THE WATER PRODUCED IS STORED IN THE FIRST TANK CONTAINING HYDROGEN. THE FUEL CELL MODULE IS PLACED IN A CONTAINMENT VESSEL WHICH IS PRESSURIZED WITH NITROGEN. A CATALYTIC REACTOR IS PROVIDED IN THE CONTAINMENT VESSEL TO FORM WATER IN THE EVENT THAT THERE ARE SIMULTANEOUS LEAKS IN BOTH THE HYDROGEN AND OXYGEN HIGH PRESSURE SUPPLY LINES. A PRESSURE TRANSDUCER IS ALSO PROVIDED IN THE CONTAINMENT VESSEL FOR SHUTTING DOWN THE SYSTEM IF THERE IS A HIGH PRESSURE LEAK IN EITHER THE HYDROGEN OR OXYGEN LINE.
