최근 환경과 에너지 개발에 대한 국가와 사회의 관심이 집중되면서 자동차, 선박, 항공과 같은 다양한 산업분야에 연료전지를 동력장치로 활용하기 위한 연구가 활발히 이루어지고 있다. 특히 고분자 전해질막 연료전지(PEMFC: Polymer Electrolyte Membrane Fuel Cell, Proton Exchange Membrane Fuel Cell)는 작동 온도가 낮고 동력밀도가 높아, 넓은 범위에서 활용 가능성이 큰 연료전지로 평가받고 있다. 그러나, 고분자 전해질막 연료전지는 수소를 연료로 사용하기 때문에 에너지 밀도를 높이기 위해서는 고밀도의 수소 저장 기술이 필수적으로 요구된다.Recently, as the attention of the state and society on the environment and energy development has been concentrated, researches for actively using fuel cells as power devices in various industries such as automobiles, ships, and aviation have been actively conducted. In particular, polymer electrolyte membrane fuel cells (PEMFC) and proton exchange membrane fuel cells (PEMFC) have low operating temperatures, high power density, and are widely evaluated as fuel cells that can be widely used. However, since the polymer electrolyte membrane fuel cell uses hydrogen as a fuel, high density hydrogen storage technology is required to increase energy density.
수소 저장 기술에는 압축, 액체 수소, 탄화수소 개질, 금속 수소화물, 화학적 수소화물 등의 저장 기술이 있다. 압축 저장은 700기압의 높은 충전 압력, 액체 수소는 -252.7°C의 낮은 온도로 저장되므로 불안정성 및 고가격 문제가 남아있다. 탄화수소 개질은 개질 온도가 높고 부수적인 일산화탄소 처리과정이 필요하기 때문에, 처리 시스템이 복잡하다는 문제가 있다. 또한, 금속 수소화물은 중량이 무겁고 부피가 크기 때문에 높은 에너지 밀도를 기대하기 어렵고 특히 휴대용 연료전지의 경우 안정성 및 편의성에 문제가 있다.Hydrogen storage techniques include compression, liquid hydrogen, hydrocarbon reforming, metal hydrides, chemical hydrides and the like. Compressed storage has a high filling pressure of 700 atm, and liquid hydrogen is stored at a low temperature of -252.7 ° C, leaving instability and high price issues. Hydrocarbon reforming has a problem that the processing system is complicated because the reforming temperature is high and ancillary carbon monoxide treatment is required. In addition, since metal hydride is heavy and bulky, it is difficult to expect a high energy density, and particularly in the case of a portable fuel cell, there is a problem in stability and convenience.

In particular, among various chemical hydrides, sodium borohydride (NaBH 4 ) is a stable incombustible alkaline solution, which is easy to store and handle.

화학식 1은 수소화붕소나트륨(NaBH4)으로부터 수소를 생성하기 위한 화학식이다. 따라서 수소화붕소나트륨(NaBH4)을 사용한 수소 발생 방식은, 반응 후 생성된 가스가 오직 수소뿐이므로 순수한 수소를 추가적인 공정 없이 얻을 수 있다. 또한, 상온에서도 발열반응이 일어나므로 추가적인 열 공급이 필요 없기 때문에 시스템이 간단하고 연료전지와의 통합이 용이하다.Formula 1 is a formula for producing hydrogen from sodium borohydride (NaBH 4 ). Therefore, the hydrogen generation method using sodium borohydride (NaBH 4 ), since the only gas produced after the reaction is hydrogen, pure hydrogen can be obtained without further processing. In addition, since the exothermic reaction occurs at room temperature, no additional heat supply is required, thereby simplifying the system and facilitating integration with the fuel cell.
또한, 수소화붕소나트륨(NaBH4)을 사용한 화학수소화물 수소 발생기는 휴대용 소형 연료전지에 적용이 용이하다. 그러나 수소 발생 장치의 연료 저장 챔버, 촉매 반응부, 수소 저장 챔버, 부산물 임시 저장 챔버, 부산물 저장 챔버 등의 구조가 일체형으로 통합되어 구성되지 않으면 높은 에너지밀도를 얻기 어려운 문제가 있다. 또한, 부산물인 메타붕산나트륨(NaBO2)을 주기적으로 제거 또는 배출하지 못하면 촉매의 피독 및 배출구의 막힘과 같은 문제점이 발생한다.In addition, the chemical hydride hydrogen generator using sodium borohydride (NaBH 4 ) is easy to apply to a portable small fuel cell. However, unless the structure of the fuel storage chamber, the catalytic reaction unit, the hydrogen storage chamber, the by-product temporary storage chamber, the by-product storage chamber, etc. of the hydrogen generator is integrated integrally configured, there is a problem that it is difficult to obtain a high energy density. In addition, failure to periodically remove or discharge byproduct sodium metaborate (NaBO 2 ) causes problems such as poisoning of the catalyst and blockage of the outlet.

A by-product storage chamber of rubber material is provided in the fuel chamber and is connected between the by-product temporary storage chamber and the by-product discharge valve. Therefore, a large amount of fuel can be stored in the fuel chamber and supplied to the catalytic reaction unit as compared with the hydrogen generator of FIG. 2. In addition, since the by-product storage chamber of the rubber material can store the by-product in the empty volume space generated by the use of fuel, it is easy to utilize the space of the fuel chamber and the by-product storage chamber.
