The hydrogen gas storage tank comprises a body comprising a steel bulk region and a passivating metal oxide layer adjacent the steel bulk region, wherein the oxide layer includes a plurality of metal oxide molecules all having a shape, at least about 51% by weight of the number of metal oxide molecules are Fe_2O_3 molecules having a form of (012), (001) and/or (110) surface facets, and the oxide layer is thereby configured to lower hydrogen adsorption into the steel bulk region by at least 25% compared to the steel bulk region without the passivating metal oxide layer. 수소 가스 저장 탱크는 강 벌크 영역 및 상기 강 벌크 영역에 인접한 부동태화 금속 산화물층을 포함하는 몸체를 포함하며, 상기 산화물층은 모두 형태를 갖는 복수의 금속 산화물 분자들을 포함하며, 상기 금속 산화물 분자들의 수의 적어도 약 51 중량%가 (012), (001) 및/또는 (110) 표면 파셋(facet)의 형태를 갖는 Fe2O3 분자이며, 이로써 상기 산화물층은 상기 부동태화 금속 산화물층이 없는 강 벌크 영역에 비해 상기 강 벌크 영역으로의 수소 흡착을 적어도 25%만큼 낮추도록 구성된다.
