Abstract: One or more indicators provide an indication of fueling status of a hydrogen powered vehicle. One or more sensors detect temperature and/or other characteristics of the fuel provided to the vehicle and provide an electrical signal to one or more of the indicators to permit an indication of fueling status. The indicators, which may be visual and/or audible, may be positioned on the fueling apparatus and on the vehicle in the vicinity of a fueling receptacle. The indicators may also be positioned elsewhere on the vehicle and may be separate from the vehicle such as on or around a fueling station and/or on separate computerized devices.
