A hydrogen supply system is provided which can supply hydrogen easily to a hydrogen storing means, can generate a gas containing hydrogen at a low temperature and uses a hydrogen generating device which does not require a large quantity of electric energy. In a hydrogen supply system comprising at least hydrogen supply means for supplying hydrogen to hydrogen storing means such as a hydrogen storage container loaded on a fuel cell automobile, for example, and a hydrogen generating device ( 10 ) for generating a gas containing hydrogen to be supplied to the hydrogen supply means, the hydrogen generating device is to generate the gas containing hydrogen by decomposing a fuel containing an organic compound, comprising a partition membrane ( 11 ), a fuel electrode ( 12 ) provided on one surface of the partition membrane, means ( 16 ) for supplying a fuel containing the organic compound and water to the fuel electrode, an oxidizing electrode ( 14 ) provided on the other surface of the partition membrane, means ( 17 ) for supplying an oxidizing agent to the oxidizing electrode, and means for generating and collecting the gas containing hydrogen from the fuel electrode. There are cases: (1) the hydrogen generating device is an open circuit having neither means for withdrawing electric energy to outside from a hydrogen generating cell constituting the hydrogen generating device, nor means for providing electric energy from outside to the hydrogen generating cell; (2) the hydrogen generating device has means for withdrawing electric energy to outside with the fuel electrode serving as a negative electrode and the oxidizing electrode as a positive electrode; and (3) the hydrogen generating device has means for providing electric energy from outside with the fuel electrode serving as cathode and the oxidizing electrode as anode.
