Abstract: Disclosed herein are mobile hydrogen gas dispensing apparatus, and methods for dispensing hydrogen gas. In one embodiment, the mobile hydrogen gas dispensing apparatus comprises a first outlet and a second outlet. The first outlet comprises a first valve, a first hydrogen gas output port, a first nozzle, a first display panel in operable communication with the first hydrogen gas output port, and a first hose forming fluid communication between the first hydrogen output port and the first nozzle. The apparatus further comprises: an electrochemical cell disposed in fluid communication with the first outlet, and a mobile platform, wherein the first outlet and the electrochemical cell are mechanically connected to the mobile platform.

Abstract: In one embodiment, the method of dispensing hydrogen gas comprises: selecting a hydrogen gas pressure using a pressure selector disposed in operable communication with a hydrogen gas output port, dispensing hydrogen gas at the selected hydrogen gas pressure, ceasing a flow of hydrogen gas to the vessel, and removing the nozzle from fluid communication with the vessel. The nozzle is in fluid communication with a hose and the hydrogen gas output port to form a first outlet disposed in mechanical connection with a mobile platform. In yet another embodiment, the method of dispensing hydrogen gas comprises: producing the hydrogen gas in an electrolysis cell system, activating a hydrogen dispenser, dispensing the hydrogen gas to a vessel, and ceasing a flow of the hydrogen gas to the vessel. The hydrogen dispenser and the electrolysis cell system are on a mobile platform.

Abstract: Disclosed herein are an electrochemical system, a hydrogen gas fueling system, a cascade system, and methods for using the same. The hydrogen gas fueling system comprises a multiple-stage compressor disposed in fluid communication with a hydrogen gas source, the compressor configured to cool hydrogen gas received at a stage of the compressor, a cascade section comprising at least two hydrogen gas storage zones disposed in fluid communication with the compressor at the outlet of the compressor, and a hydrogen gas dispensing section disposed in fluid communication with the cascade section.

Abstract: The present invention is a pre-assembled fitting or coupling having a body, a sleeve, and a nut. One end of the nut has a through bore that is tapered and decreases in diameter toward the end of the nut. The outer surface of the sleeve is tapered as well which facilitates the radial movement of the sleeve segments upon tightening locking the sleeve segments into the proper position on the corrugated tubing. The body contains an inner seal surface with improved geometry that effectively concentrates the sealing load over a pre-determined surface and prevents overloading of the seal surface area. The sleeve of the present invention is divided into four separate segments. The inner surface of the sleeve contains an annular spring. The spring on the inner surface facilitates the removal of the corrugated tube from the nut and coupling body by forcing the segments outward upon loosening the nut.
