Abstract: Hydrogen refueling station, hydrogen-powered vehicle, and hydrogen refueling system are provided. The hydrogen refueling system comprises a decomposition device, a transfer device, a storage device, and a recombination device; wherein the decomposition device is configured to decompose water into hydrogen and oxygen; the transfer device is configured to deliver the hydrogen into the storage device and to discharge the oxygen into an environment; the storage device is configured to store the hydrogen delivered from the transfer device; the recombination device is configured to receive the hydrogen from the storage device and the oxygen from the environment, the hydrogen and oxygen reacting in the recombination device to produce an electric current. The hydrogen refueling system adopts real-time hydrogen production and refueling, thereby eliminating the need to construct large hydrogen storage tanks, and the need for the long-distance transportation of the hydrogen.
