Summary:To provide a technology capable of effectively suppressing deterioration of a water electrolysis stack in a hydrogen production system that produces hydrogen using a plurality of water electrolysis stacks.SOLUTION: In a hydrogen production system 1, a power distribution control system 14 formulates an operation rotation plan for a water electrolysis stack on the basis of the deterioration characteristics that indicate the susceptibility of the water electrolysis stack to deterioration. According to this operation rotation plan, the operation state of the water electrolysis stack is assigned to either an operation priority stack that preferentially receives power, a stop priority stack that stops for a long period of time, or an intermediate operation stack.SELECTED DRAWING: Figure 1 【課題】複数の水電解スタックを用いて水素を製造する水素製造システムにおいて、水電解スタックの劣化を効果的に抑制することができる技術を提供する。【解決手段】水素製造システム1において、電力分配制御システム14は、水電解スタックの劣化のしやすさを示す劣化特性に基づき水電解スタックの稼働ローテーション計画を策定する。この稼働ローテーション計画により水電解スタックの動作状態は、優先的に電力を受ける稼働優先スタック、長い期間停止する停止優先スタック又は中間稼働スタックのうちいずれかに割り当てられる。【選択図】図1
