1. A system for generating hydrogen, comprising:
an ammonia decomposition bed configured to: introduce an ammonia gas, decompose the ammonia gas into a high-pressure first mixed gas including nitrogen and hydrogen, and discharge the high-pressure first mixed gas;
an ammonia adsorption bed supplied with the high-pressure first mixed gas from the ammonia decomposition bed, and configured to: adsorb residual ammonia of the high-pressure first mixed gas, and discharge a high-pressure second mixed gas including nitrogen and hydrogen; and
a nitrogen adsorption bed directly supplied with the high-pressure second mixed gas from the ammonia adsorption bed, and configured to: adsorb the nitrogen, and discharge the hydrogen,
wherein:
the ammonia adsorption bed includes a plurality of first bed modules, and the plurality of first bed modules each configured to independently perform an ammonia adsorption process, an ammonia desorption process, and a cleaning process.
