Abstract: The present invention relates to a hydrogen production reactor comprising a high-efficiency composite having a high thermal conductivity and an antioxidant property. Specifically, the hydrogen production reactor comprises: a first region in which a combustion reaction of fuel occurs; a second region in which a hydrogen extraction reaction occurs; a metal substrate that partitions the first region and the second region; and a coating layer that comprises boron nitride (BN) and is formed on at least one surface of the metal substrate, wherein heat generated in the first region is transferred to the second region through the metal substrate.
