<P>PROBLEM TO BE SOLVED: To provide a hydrogen-supplying device with the use of solid polymer type water electrolysis cell, which controls the total of a facility cost and power consumption for obtaining a high-pressure hydrogen gas having 40 to 120 MPa, to a low level. <P>SOLUTION: The device comprises: a pressure vessel 3 which accommodates a water electrolysis cell 2 and is kept at a predetermined pressure; at least one compressor 34 for pressurizing hydrogen gas taken out from the pressure vessel 3; and a dispenser 38 for supplying the pressurized hydrogen gas. The pressure vessel 3 is designed to endure the pressure of 5 to 20 MPa, and the compressor 34 pressurizes hydrogen gas to 40 to 120 MPa, from 5 to 20 MPa. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
