A hydrogen generating apparatus and a fuel cell power generation system are disclosed. The hydrogen generating apparatus may include: an electrolyte bath, which contains an electrolyte solution; a first electrode, which is coupled to one side within the electrolyte bath, and which is configured to generate electrons; and a second electrode, which is coupled to the one side within the electrolyte bath with a predetermined distance from the first electrode, and which is configured to generate hydrogen using the electrons and the electrolyte solution. The apparatus can be structured to have electrodes and conductive coating layers secured to the inside of the electrolyte bath, to reduce resistance between the electrodes and an external circuit and facilitate the movement of electrons.
