Abstract
A gating device (100) and associated method (900) for identifying a fuel container (101) used to refill a fuel cell (102) are presented. A fuel source identification device (103) identifies a fuel container (101) to verify that it is compatible with the fuel cell (102). Upon identification, a gating engine (105) opens a retractable barrier (106), thereby providing access to the fuel cell (102). The gating engine (105) moves the retractable barrier (106) from a closed position to an open position when a control circuit (803) indicates that the fuel container (101) is compatible with the fuel cell (102). The fuel container identification device may be an impedance detector (201), a connectivity detector (301), a barcode reader (401), a memory reader (501), a radio-frequency identification device (601), a label reader (701), or other similar device.
