Abstract
Electrochemical systems and methods of operating the systems are disclosed herein. In one embodiment, a method for operating an electrochemical system, comprises: forming hydrogen gas in an electrolysis cell, maintaining the hydrogen gas at a temperature sufficient to enable the filling of a hydrogen gas vessel at a rate that would fill a 5 kg vessel with the hydrogen gas in a period of time of less than or equal to about 10 minutes, and introducing the hydrogen gas to the hydrogen gas vessel.
Claims15
A method for filling a hydrogen gas vessel, comprising:
- passing hydrogen gas from a hydrogen gas source to a hydrogen gas vessel;
- and
- maintaining the hydrogen gas at a temperature sufficient to enable the filling of the hydrogen gas vessel at a rate that would fill a 5 kg vessel with the hydrogen gas in a period of time of less than or equal to about 10 minutes.
A method for operating an electrochemical system, comprising:
- forming hydrogen gas in an electrolysis cell;
- cooling the hydrogen gas to a non-cryogenic temperature;
- and
- introducing the cooled hydrogen gas to a vessel.
An electrochemical cell system, comprising:
- an electrolysis cell;
- a heat exchanger downstream of the electrolysis cell;
- and
- a sensor configured to be disposed in communication with at least one of a hydrogen gas vessel to be filled and a point both upstream of the hydrogen gas vessel and downstream of the heat exchanger, wherein the sensor is disposed in operable communication with the heat exchanger.
A storage medium encoded with a machine readable computer program code, the code including instructions for causing a computer to implement a method for operating an electrochemical system, the method comprising:
- passing hydrogen gas from a hydrogen gas source to a hydrogen gas vessel;
- and
- maintaining the hydrogen gas at a temperature sufficient to enable the filling of the hydrogen gas vessel at a rate that would fill a 5 kg vessel with the hydrogen gas in a period of time of less than or equal to about 10 minutes.
A computer data signal, the computer data signal, comprising:
- instructions for causing a computer to implement a method for operating an electrochemical system, the method comprising:
- passing hydrogen gas from a hydrogen gas source to a hydrogen gas vessel;
- and
- maintaining the hydrogen gas at a temperature sufficient to enable the filling of the hydrogen gas vessel at a rate that would fill a 5 kg vessel with the hydrogen gas in a period of time of less than or equal to about 10 minutes.
A method for filling a hydrogen gas vessel, comprising:
- passing hydrogen gas from a hydrogen gas source to the hydrogen gas vessel;
- and
- controlling a temperature of the hydrogen gas to fill the vessel to its specification pressure and maximum volume capacity while maintaining a vessel pressure at less than or equal to the specification pressure.
