A method and apparatus for refueling a vehicle powered by an electrochemical engine comprises a fuel fill pocket accessible to the exterior of the vehicle and having an interior end with an opening to a hydrogen refueling line. The hydrogen refueling line extends between the fuel fill pocket and a storage tank in the engine. A fuel fill door conceals the fuel fill pocket when closed and operates to open for access to the fuel fill pocket. A nozzle is operably connected to a refueling station and is slideably receivable within the fuel fill pocket. The nozzle has a hydrogen input line. The refueling apparatus has a flow communication means to ensure the hydrogen input line is in flow communication with the hydrogen refueling line for delivering hydrogen. Mating communication ports in the nozzle and the fuel fill pocket operate to send and receive electronic signals therebetween and to a controller for controlling the operation of refueling. The controller ensures that the nozzle is properly inserted before initiating refueling and verifies that line pressures are below a minimum set level before the nozzle may be removed from the fuel fill pocket.
