Abstract: The present invention aims to provide a hydrogen generating method for generating hydrogen-containing gas little contaminated with nitrogen, CO, etc., by decomposing fuel containing an organic compound at low temperature while requiring the supply of no or little electric energy from an external source, and a hydrogen generating system based on the method. A hydrogen generating system based on the method can work under multiple conditions: (a) it works under a condition where electric energy is withdrawn from the hydrogen generating cell with the fuel electrode (12) serving as a negative electrode and the oxidizing electrode (14) as a positive electrode; and (b) it works under another condition where external electric energy is provided to the hydrogen generating cell with the fuel electrode (12) serving as cathode and the oxidizing electrode (14) as anode.
