Abstract
Official abstract text for this publication.
A water electrolysis system includes a high-pressure hydrogen production unit for electrolyzing water to generate oxygen and high-pressure hydrogen (the pressure of the high-pressure hydrogen being higher than that of the oxygen), and a gas-liquid separation unit for removing water contained in the high-pressure hydrogen. The gas-liquid separation unit is placed on a hydrogen pipe for discharging the high-pressure hydrogen from the high-pressure hydrogen production unit. In addition, the water electrolysis system includes a high-pressure hydrogen supply pipe for transferring dewatered high-pressure hydrogen from the gas-liquid separation unit, a cooling unit, which is placed on the high-pressure hydrogen supply pipe and is capable of variably controlling the temperature of the high-pressure hydrogen to adjust the humidity of the high-pressure hydrogen, and a control unit.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for operating a water electrolysis system, wherein the water electrolysis system contains: a high-pressure hydrogen production unit for electrolyzing water, thereby generating oxygen at an anode side and generating hydrogen at a cathode side; a hydrogen storage unit for storing hydrogen discharged from the high-pressure hydrogen production unit; a hydrogen supply pipe for supplying hydrogen generated in the high-pressure hydrogen production unit…
