Abstract
A hydrogen gas production apparatus 1 includes: a vaporizer 5 configured to generate ammonia gas by heating liquid ammonia; a main thermal decomposition device 6 configured to decompose the ammonia gas generated in the vaporizer 5, into nitrogen gas and hydrogen gas, by heating the ammonia gas by causing a fuel gas to burn; a cooler 7 configured to cool a decomposition gas including the nitrogen gas and the hydrogen gas generated through the decomposition in the main thermal decomposition device 6; and a separator 8 configured to separate hydrogen gas from the decomposition gas having been cooled.
