An intelligent fuel storage system can consist of a storage pod connected to a storage module with the storage pod having a plurality of separate storage vessels each residing below a ground level. The storage pod may concurrently store a first volume of a first fuel and a second volume of a second fuel prior to altering the first and second volumes in accordance with a performance strategy generated by the storage module to provide a predetermined blend of the first fuel and second fuel with at least a threshold volume and at least a threshold pressure.

A combustion powered tool uses a fuel canister with a refillable hydrogen storage vessel containing metal hydride. The fuel canister includes a valve assembly with at least one valve to release hydrogen fuel gas. The valve assembly is removable from the refillable hydrogen storage vessel. A coupling device includes a first coupler attached to the refillable hydrogen storage vessel and a second coupler attached to the valve assembly. An outlet adapter is attached to the valve assembly to supply hydrogen fuel gas to the power tool.

An integrated pressure regulator is provided with three stages configured to reduce an extreme tank pressure down to a typical working pressure. The regulator is configured to supply a steady working pressure until the tank pressure is reduced to little more than the working pressure itself. Stages of the pressure regulator are integrated into a body and arranged to minimize regulator mass and volume. A thermally-triggered pressure relief device may be included with a triggering time adapted to enhance the safety of smaller cylinders that may be used, e.g., in aerial applications.

Various embodiments of the present disclosure provide a combustion-powered fastener driving tool fuel cell assembly including a fuel cell, fuel cell adapter, and fuel cell adapter cap for a combustion-powered fastener driving tool. The fuel cell, the fuel cell adapter, and the fuel cell adapter cap enable both the fuel cell adapter and the fuel cell adapter cap to be attached to a fuel cell and particularly a sealing member of the fuel cell in one efficient step. This single step process can be done manually or automatically, and is substantially more efficient and less time-consuming than the known fuel cell assemblies.

A hydrogen filling method for a fuel cell vehicle includes filling a hydrogen tank of the fuel cell vehicle with hydrogen using a hydrogen dispenser by sequentially using a low-pressure storage tank of the fuel cell vehicle, a medium-pressure storage tank of the fuel cell vehicle, and a high-pressure storage tank of the fuel cell vehicle.

A method of manufacturing a high pressure tank includes: preparing a liner; forming a fiber reinforced resin layer which is a layer of a fiber reinforced resin on an outer side of the liner, and forming a resin layer which is a layer formed of a portion of a thermosetting resin on an outer surface of the fiber reinforced resin layer; increasing a temperature of the fiber reinforced resin layer and the resin layer to a predetermined temperature which is a temperature at which the thermosetting resin is cured; causing a pressure in the liner to be regulated to be a second pressure higher than a first pressure which is a pressure in the liner in the forming of the fiber reinforced resin layer and the resin layer; and maintaining the temperature of the fiber reinforced resin layer and the resin layer at the predetermined temperature.

According to at least one aspect, a hydrogen gas dispensing system is provided. The hydrogen gas dispensing system includes a source configured to provide a hydrogen gas, a storage device configured to store the hydrogen gas up to a first pressure level, a dispenser configured to dispense the hydrogen gas up to a second pressure level that is higher than the first pressure level, and a compressor configured to compress the hydrogen gas from the source up to the first pressure level for storage in the storage device and configured to compress the hydrogen gas from the storage device up to the second pressure level for dispensing via the dispenser. According to at least one aspect, the dispensing system comprises an input power port configured to receive input power and an output power port configured to deliver output power derived from the input power to charge an electric vehicle.

An integrated pressure regulator is provided with three stages configured to reduce an extreme tank pressure down to a typical working pressure. The regulator is configured to supply a steady working pressure until the tank pressure is reduced to little more than the working pressure itself.

A tank has a body defining a chamber therein, the chamber is configured to store a gas at a pressure greater than atmospheric pressure, a first mounting element extending from the body, and a second mounting element extending from the body. The first mounting element and the second mounting element are configured for coupling to a first component of a vehicle and a second component of the vehicle, respectively, and the body is configured to carry a structural load between the first component and the second component when the first mounting element and the second mounting element are coupled thereto. The first component carries a propulsion device and the second component comprises at least one of a wing and a landing element. The tank further includes a stem having an orifice and the stem is configured for delivering the gas to the propulsion device through the orifice.

A pressure relief device includes a housing member having an inner space, a piston member provided in the inner space of the housing member, and a fusible member provided in a region below the piston member. The piston member includes an upper end region formed at an upper end in the up-down direction (H), and a connection region which is formed below the upper end region and extends downward from the upper end region while being connected to the upper end region. A first width (W1) of the upper end region in a left-right direction (A) is equal to a second width (W2) of the connection region in the left-right direction (A) or less than the second width (W2).
