Abstract
A mobile self-contained self-powered station having a plurality of vessels delivers a pressurized fluid to a receiving tank (e.g., a fuel tank of a hydrogen-powered vehicle) without using mechanical compression, external electric power, or other external utilities. The station includes first and second vessels, a conduit in fluid communication with the receiving tank and each of the first and second vessels, means for transferring at least a portion of a quantity of the pressurized fluid from the first vessel to the receiving tank, means for measuring continuously a pressure differential between the increasing pressure in the receiving tank and the decreasing pressure in the first vessel, means for discontinuing the transfer from the first vessel when a predetermined limit value is reached, and means for transferring at least a portion of a quantity of the pressurized fluid from the second vessel to the receiving tank.
