Abstract
An apparatus and method for providing a hydrogen rich gas stream at a high pressure for use by hydrogen vehicles or other devices requiring hydrogen rich feed streams are disclosed in the present invention. As the pressure of gaseous hydrogen is increased, the temperature of the gaseous hydrogen also increases due to the heat of compression. The apparatus and method of the present invention utilize localized cooling via a vortex tube to cool the gaseous hydrogen caused by the increase in pressure.
