Methods for Dispensing Hydrogen Gas

1 . A method of dispensing hydrogen gas, comprising:

selecting a hydrogen gas pressure using a pressure selector disposed in operable communication with a hydrogen gas output port;

disposing a nozzle in fluid communication with a vessel to receive the hydrogen gas;

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;

wherein 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.

2 . The method of claim 1 , further comprising vertically actuating the first outlet.

3 . The method of claim 1 , wherein the selected pressure is about 2,700 psi to about 4,500 psi.

4 . The method of claim 1 , wherein the selected pressure is about 3,700 psi to about 6,750 psi.

5 . The method of claim 1 , wherein the first outlet further comprises a valve, and further comprising actuating the valve.

6 . The method of claim 1 , further comprising adjusting a hydrogen gas fill pressure to the selected pressure.

7 . A method of dispensing hydrogen gas, comprising:

disposing a first nozzle of a first outlet in fluid communication with a vessel to receive the hydrogen gas, wherein the first outlet comprises the first nozzle in fluid communication with a first hydrogen output port, wherein the first hydrogen output port is in operable communication with a first display panel, and wherein the first nozzle, the first hydrogen output port, the hydrogen gas, and the first display panel, are on a mobile platform;

dispensing the hydrogen gas;

ceasing a flow of the hydrogen gas to the vessel; and

removing the nozzle from fluid communication with the vessel.

8 . The method of claim 7 , further comprising dispensing additional hydrogen gas from with a second outlet, and wherein the first outlet and the second outlet are dispensing hydrogen gas at different fill pressures.

9 . The method of claim 8 , wherein a first outlet pressure is about 2,700 psi to about 4,500 psi, and wherein a second outlet pressure is about 3,700 psi to about 6,750 psi.

10 . The method of claim 7 , further comprising vertically actuating the first outlet.

11 . A method of dispensing hydrogen gas, comprising:

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;

wherein the hydrogen dispenser and the electrolysis cell system are on a mobile platform.

12 . The method of claim 11 , wherein the hydrogen gas is dispensed with a first outlet, and further comprising dispensing additional hydrogen gas with a second outlet, and wherein the first outlet and the second outlet are dispensing hydrogen gas at different fill pressures.

13 . The method of claim 12 , wherein a first outlet pressure is about 2,700 psi to about 4,500 psi, and wherein a second outlet pressure is about 3,700 psi to about 6,750 psi.

14 . The method of claim 11 , wherein activating the hydrogen dispenser further comprises vertically actuating a first outlet.

15 . The method of claim 11 , wherein activating the hydrogen dispenser further comprises selecting a hydrogen gas pressure using a pressure selector disposed in operable communication with a hydrogen gas output port.

16 . The method of claim 11 , wherein producing the hydrogen further comprises introducing water to the electrolysis cell system.
