Abstract: A method and apparatus for cooling a compressed fuel gas during transfer of the gas from a source vessel to a receiving vessel. The method includes receiving a portion of the fuel gas from the source vessel in an intermediate vessel. Then, fluidly isolating the intermediate vessel from the source vessel. Work is then extracted from the fuel gas by causing or allowing expansion of the fuel gas, thereby cooling the fuel gas. Finally, the cooled portion of fuel gas is released from the intermediate vessel to the receiving vessel.

Abstract: A method and apparatus for comparing fuel sources to assess the suitability of a fuel for use in a fuel cell. The apparatus comprising an electrochemical sensor comprising a fuel flow channel configured to receive a plurality of input fuels at a plurality of locations along the fuel flow channel. The fuel flow channel configured to supply the plurality of input fuels to an anode of the electrochemical sensor and an electrolyte configured to transmit ionised input fuels from the anode to a cathode of the electrochemical sensor. A control system connected to the electrochemical sensor where the anode and/or the cathode is divided into a plurality of segments and the control system is configured to measure the current in each of the plurality of segments and determine the current density of each of the plurality of segments.

Abstract: A modular blending system is shown and described. The modular blending system may include a storage device capable of storing a plurality of flavoring products, and an ice shaving mechanism removably attached to the storage device, the ice shaving mechanism including an ice dispenser. The modular blending system may also include a fluid dispensing unit in fluid communication with the flavoring products, where the fluid dispensing unit is separate from the ice dispenser.
