Abstract: A method and system for automatically calibrating a pressure sensor in a hydrogen storage system for a fuel cell vehicle. A low-range pressure sensor in the fuel cell system, which has much greater accuracy at low pressure readings, is used to calibrate a high-range pressure sensor in the hydrogen storage system. This calibration can only be done when a pressure regulator situated between the two sensors is in a fully open position. In such a condition, the high-range sensor can be calibrated to the value of the low-range sensor, thus improving the accuracy of the high-range sensor's readings. The calibration can be a simple setting of the high-range sensor to the value of the low-range sensor under static conditions, or the calibration can be done while gas is flowing from the hydrogen storage system to the fuel cell by accounting for the pressure drop between the two sensors.

Abstract: A process for manufacturing a compressed gas tank that includes a combination of an injection molding process and a rotomolding process. In a first step, a boss to be positioned in the opening of an outer structural layer of the tank is provided and a thin portion of the liner is injection molded to the boss so that a channel within the boss is filled with the liner material to increase the seal integrity between the boss and the liner.

During the rotomolding process, the injection molded portion of the liner melts to be part of the liner made during the rotomolding process.

Abstract: A device for storing compressed gas includes a cylindrical pressure vessel having inlet and outlet conduits for a cooling/heating fluid and for compressed gas. Arranged in the interior of the pressure vessel are plural storage layers which are separated from one another and contain solid matter for charging with compressed gas. The storage layers have a volume, which depends on a charging state of the storage layers with compressed gas, and are separated dust-tight from one another about their circumference. Bounding one side of each storage layer is a spring layer which assumes a filtering function with respect to the solid matter of the storage layer, wherein the solid matter in the storage layer is charged with compressed gas via the spring layer or compressed gas is discharged from the solid matter in the storage layers via the spring layer. The other opposite side of the storage layer is bounded by a gastight cooling/heating layer for passage of the cooling/heating fluid.
