The present invention relates to a method (100) for the electrolytic production of a liquid hydrogen product (4), in which a water-containing feed undergoes an electrolysis (E) while receiving an anode raw gas (3) that is rich in oxygen and contains hydrogen and a cathode raw gas (2) that is depleted of oxygen and rich in hydrogen, wherein the cathode raw gas (2) undergoes a purification (R), a compression (K), and a liquefaction (L) at the downstream of the electrolysis (E). Accordingly, the cathode raw gas (2) at least partially undergoes intermediate storage (Z) at the downstream of the electrolysis (E) and upstream of the liquefaction (L). A corresponding installation is also suggested. 본 발명은 액체 수소 생성물(4)의 전기분해 제조를 위한 방법(100)에 관한 것으로서, 물-함유 공급물은 산소가 풍부하고 수소를 함유하는 애노드 원시 가스(3) 및 산소가 고갈되고 수소가 풍부한 캐소드 원시 가스(2)를 수용하면서 전기분해(E)를 겪고, 캐소드 원시 가스(2)는 전기분해(E)의 하류에서 정제(R), 압축(K), 및 액화(L)를 겪으며, 캐소드 원시 가스(2)는 전기분해(E)의 하류 및 액화(L)의 상류에서 적어도 부분적으로 중간 저장(Z)을 겪는 것을 특징으로 한다. 대응하는 설비가 또한 제안된다.
