Technologies are described herein for conditioning fluids stored in an underwater cryogenic storage vessel designed for use in a fuel system of an underwater vehicle. According to one aspect of the disclosure, a fuel system includes a fuel cell and a storage vessel, which stores a first fluid that is supplied to the fuel cell and a second fluid that is produced by the fuel cell. The fuel system also includes a thermal conditioning module that receives the first fluid from the storage vessel and receives the second fluid from the fuel cell. The first fluid stored in the storage vessel is conditioned by absorbing heat from the second fluid, such that the fuel cell receives the conditioned first fluid. The second fluid received from the fuel cell is in gaseous state and is converted to a liquid. The liquid second fluid is stored in the storage vessel.
