The new idea of submarine oxygen and fuel management involves a water filter that rests on the exoskeleton of the sub just underneath and is bolted with connection to the sub oxygen management system with pipes, caulking and O rings of course that will be plugged into the sub's oxygen management system with micro-piping. The purpose will be to avoid unnecessary resurfacing for oxygen. It will also extract hydrogen from the water that will be used to fuel the fuel cell. Next; think of a diver with a diving oxygen mask on. But, what if he did not need tanks and the new masks could just extract oxygen from the water? This may take some time so we can work on a fuel cell oxygen extractor that would take oxygen out of the water and rest on his back like the current air tanks. Instead of heavy air tanks, one small hydrogen tank with a fuel cell could power the new air lung. As this will work, it could be used on a submarine.
