The present invention relates to a hydrogen fuel tank with excellent hydrogen storage safety due to excellent airtightness, impact resistance and durability, and a method for manufacturing the same. According to the present invention, the hydrogen fuel tank comprises: a tank body capable of storing hydrogen therein; and a hydrogen barrier layer disposed on at least one surface of the tank body. The hydrogen barrier layer includes: a first barrier layer disposed on at least one surface of the tank body and made of a (semi)metal; and a second barrier layer disposed on the first barrier layer to fill an empty space in the first barrier layer. 본 발명은 수소 연료 탱크 및 이의 제조방법에 대한 것으로, 상기 수소 연료 탱크는 내부에 수소를 저장할 수 있는 탱크 본체; 및 상기 탱크 본체의 적어도 일면 상에 배치된 수소 배리어층을 포함하고, 상기 수소 배리어층은 상기 탱크 본체의 적어도 일면 상에 배치되고, (준)금속으로 된 제1배리어층; 및 상기 제1 배리어층 상에 배치되어 상기 제1 배리어층 내 빈 공간을 충전하는 제2 배리어층을 포함한다.
