Summary:The present invention relates to a hydrogen generation system for a fuel cell, which stores substances used as chemical hydrides and decomposition agents in solid and liquid states, respectively, and supplies hydrogen generated through a decomposition reaction of the stored substances to a fuel cell, thereby reducing risk of storage, increasing storage density, facilitating recharging, and being suitable for use in a submarine, spacecraft or the like. The hydrogen generation system for a fuel cell comprises: a solid fuel storage tank for storing chemical hydrides in a solid state; a reactant storage tank for storing a reactant generating decomposition agents and oxygen during a decomposition reaction in a liquid state; a reactant decomposition chamber for generating decomposition agents and oxygen by decomposing the reactant supplied from the reactant storage tank by a catalyst stored therein; a hydrogen generation chamber for generating hydrogen through the decomposition reaction between the decomposition agents and solid chemical hydrides supplied from the reactant decomposition chamber and the solid fuel storage tank, respectively; and a control means for supplying a supply amount of the solid chemical hydrides, a supply amount of the reactant, a supply amount of the decomposition agents and an amount of hydrogen generated in the hydrogen generation chamber and oxygen generated in the reactant decomposition chamber to the fuel cell as much as needed. 본 발명은 화학 수소화물과 분해제로 사용되는 물질을 각각 고체와 액체 상태로 저장하고, 그 저장된 물질들의 분해반응을 통해 생성된 수소를 연료전지에 공급함으로써 저장 위험성이 낮고, 저장 밀도가 높으며, 재충전이 용이하여, 잠수함이나 우주선 등에 적합하게 사용할 수 있는 연료전지용 수소 발생 시스템에 관한 것으로, 화학 수소화물이 고체 상태로 저장되는 고체연료저장탱크와, 분해반응시 분해제 및 산소가 생성되는 반응물질이 액체 상태로 저장되는 반응물질저장탱크와, 상기 반응물질저장탱크로부터 공급된 반응물질을 내부에 저장된 촉매로 분해시켜 분해제와 산소가 발생되는 반응물질분해챔버와, 상기 반응물질분해챔버와 고체연료저장탱크에서 각각 공급된 분해제와 고체 화학 수소화물의 분해반응을 통해 수소가 발생되는 수소발생챔버와, 고체 화학 수소화물의 공급량, 반응물질의 공급량, 분해제의 공급량 및 수소발생챔버에서 발생된 수소와 반응물질분해챔버에서 발생된 산소를 연료전지에 필요한 만큼 공급하도록 제어하는 제어수단을 포함하여 구성된 것을 특징으로 한다.
