摘要：
A purpose of the present invention is to provide a pumpless high-pressure hydrogen supply system capable of supplying high-pressure hydrogen to a fuel cell vehicle, etc., when needed without using a compressor or the like, and a method for the system. The present invention relates to a high-pressure hydrogen supply system that obtains a mixed gas of hydrogen and carbon dioxide by dehydrogenation of formic acid using a complex catalyst, separates the hydrogen therefrom, and supplies the hydrogen at a pressure of 5 MPa or more. By obtaining the mixed gas at a pressure of 5 MPa or more by dehydrogenation and cooling the mixed gas by a separator while maintaining this pressure at 0.4 MPa or more, gas components other than hydrogen are phase separated as liquids or solids and removed. The separated hydrogen is raised in purity by pressure fluctuation adsorption, continuously sent to a pressure accumulator, and stored at a pressure of 70 MPa or more.
