PURPOSE: A humidifying device of a fuel cell is provided, to control the amount of the vapor supplied to a stack effectively by generating and supplying vapor by using an oscillator. CONSTITUTION: The humidifying device comprises a stack which comprises a fuel electrode where hydrogen or a hydrogen-containing fuel material is supplied, an air electrode where an oxygen-containing oxidizing agent is supplied and an electrolyte membrane placed between the two electrodes, and generates the electricity and the heat by the electrochemical reaction of the hydrogen of the fuel material and the oxygen of the oxidizing agent; and a humidifying part(20) which contains an oscillator(23) generating the vapor supplied to the stack. Preferably the humidifying part(20) comprises a water tank(21); a purified water supply channel(22) for supplying the purified water to the water tank; an oscillator(23) mounted in the inside of the water tank for generating vapor particles; and a vapor supply channel(24) for supplying vapor to the stack. |
