A system 10 is provided for recovering the potential energy of a hydrogen gas fuel supply within a fuel cell powered vehicle 14. The system 10 includes a conventional storage tank 16 which receives and stores hydrogen gas at a relatively high pressure, an energy conversion unit or assembly 18, a compressor unit or assembly 20, pressure regulators 22, 24, a valve 26, an electrical charge storage device or battery 28, a controller 30, vehicle sensors 32 and electrical switches or switching module 34. The system 10 selectively channels pressurized hydrogen gas through energy conversion unit 18 which lowers the pressure of the hydrogen gas and generates electricity. Controller 30 causes the generated electricity to be selectively communicated to compressor 20, electrical accessories 72, and/or to battery 28 by use of switching module 34, based upon vehicle attribute data received from sensors 32.
