General Motors is going for a dip. The automaker has begun working with the U.S. Navy to develop a hydrogen-powered underwater drone. The unmanned undersea vehicle is being designed for stealthy reconnaissance missions that can last for months at a time.

For the project, GM provided a version of the hydrogen fuel cell stack that it originally engineered for automotive use. The system uses a catalyst to combine hydrogen and oxygen to form water, the chemical reaction producing electricity as a byproduct.
