    Abstract: A method of storing and using natural gas (NG) in a vehicle includes selecting a vehicle having an NG tank for fueling an engine of the vehicle. The tank service pressure rating is 3600 psi (pounds per square inch) and an NG adsorbent is in the tank. A first quantity of NG is transferred into the tank from a first source having a first source pressure less than 725 psi. The adsorbent adsorbs a portion of the NG. After transferring the first quantity of NG, the engine is operated until NG is desorbed and consumed by the engine. NG is transferred into the tank from a second source to fill the tank to a second tank pressure of about 3600 psi. The adsorbent adsorbs some of the NG. After transferring the second quantity of the NG, the engine is operated until NG is desorbed and consumed by the engine.

    Abstract: A natural gas storage system includes a container, a natural gas adsorbent positioned in the container, and a heating mechanism operatively positioned to selectively thermally activate the adsorbent. A method for improving efficiency of the natural gas storage system is also disclosed. A predetermined percentage of a capacity of the container for natural gas remaining in the container is identified. In response, a heating mechanism operatively positioned to selectively thermally activate the adsorbent is initiated. The adsorbent is heated and buffer adsorbed gas is released from the adsorbent.

    Abstract: A vehicle includes an internal combustion engine (ICE) to provide motive power to the vehicle. The ICE includes a pressurizable tank defining a tank volume to contain a solution of a natural gas and a liquid fuel. The ICE has a refueling port in fluid communication with the tank volume to selectably interface with a refueling nozzle to receive the solution from the refueling nozzle. A fuel supply tube conveys the solution from the pressurizable tank to the ICE. A fuel injector is in fluid communication with the fuel supply tube and a combustion chamber of the ICE. In response to a level of the solution in the pressurizable tank, the fuel injector is to selectably inject a predetermined quantity of the solution or a predetermined quantity of a gaseous mixture into the ICE for combustion. The gaseous mixture includes a vapor and the natural gas evaporated from the solution.

    Abstract: A tank for storing compressed natural gas (CNG) for fueling an automotive vehicle engine. The tank includes a container body for containing the CNG at a service pressure rating from about 20 MPa (megapascals) to about 30 MPa, the container body being formed from a single piece. The container body includes a head end region, a terminal end region distal to the head end region, and an intermediate region extending therebetween. The terminal end region and the head end region define an axial length of the container body. The container body is formed from an aluminum alloy. A valve member is operatively connected to, and in fluid communication with the container body via an opening defined in a wall of the container body. The container body wall has a thickness ranging from about 3 mm to about 10 mm.

    Abstract: A bipolar plate used in a fuel cell and a method of making a bipolar plate. The sheet is made from a ferritic or austenitic stainless steel, and defines an undulated surface pattern such that the patterned sheet may be formed into the bipolar plate. In one configuration, a stamping or related metal forming tool operation will further deform the patterned sheet into the bipolar plate shape such that the wall thickness is substantially uniform throughout the surface. In this way, there is a substantial reduction in stretching/thinning/necking at an intersection between bends and side walls that define the undulations of the pattern. In one form, the pattern defines a repeating serpentine shape. In a particular embodiment, the bends may include surface modifications to reduce the effects of sheet-to-tool misalignment.
