본 발명은 재생 에너지를 이용한 연료전지 생산 시스템에 관한 것으로, 더욱 상세하게는 자연 상태의 무궁무진한 친환경 재생 에너지 인것의 조력, 조류, 파력, 풍력, 태양광 재생 에너지 제공(1)하여 D.C 발전(3)하고 발생되는 전기를 해수전기분해(5)에 공급하거나 A.C 발전(2)의 전류를 얻어 D.C 변환(4)시켜 해수전기분해(9)에 사용되는 전류로 공급하여 천연적인 해수를 해수전기분해(9) 하여 수소(7), 소금(6) 산소(5)를 생성 시키는 단계The present invention relates to a fuel cell production system using renewable energy, and more particularly, to provide the tidal power, tidal current, wave power, wind power, solar renewable energy (1) of the environment-friendly renewable energy of the natural state, and DC power generation ( 3) and supply the generated electricity to seawater electrolysis (5) or obtain the current of AC power generation (2) and convert it to DC (4) and supply it as the current used for seawater electrolysis (9) Decomposition (9) to produce hydrogen (7), salt (6) and oxygen (5)

상기 단계에서 생성된 수소(7)를 분리하여 연료전지(8)에 충전하여 연료전지 생산하는 시스템의 단계를 특징으로 하는 재생 에너지를 이용한 연료전지 생산 시스템 인것이다It is a fuel cell production system using renewable energy, characterized in that the step of separating the hydrogen (7) generated in the above step to charge the fuel cell (8) to produce a fuel cell.

종래에는 연료전지에 연료로 사용되는 수소를 생산할때 여러방법이 있는데 방법중에, 염화 나트륨 등을 물에 첨가하여 D.C (직류) 전기를 흘려넣어 전기분해하면 수소가 발생 하는데 이것은 전기 소비가 많아 수소생성 비용이 석유자원 에너지 보다 커서 경제성이 없고 염화나트륨 등을 첨가하는 번거러움이 있으며, 전기분해에 사용되는 전기를 송전받아 사용 하려면 전기를 송전하는 발전처가 있어야 하는데 결국 화력발전, 엔진발전, 원자력 발전소에 의존해야 하기 때문에 청정 연료를 생산하기 위하여 결국 환경 오염원을 제공 하는 것이다Conventionally, there are many methods for producing hydrogen used as fuel in fuel cells. Among the methods, hydrogen is generated when DC (direct current) electricity is added by adding sodium chloride, etc. to water, and then electrolyzed, which generates high hydrogen consumption. Its cost is greater than that of petroleum resources, so it is not economical, and it is cumbersome to add sodium chloride.In order to receive and use electricity used for electrolysis, there must be a power source that transmits electricity. In order to produce clean fuels, eventually provide environmental pollution.

또한 수소 기체를 생성 시키기 위하여 석유자원을 이용하여 채취하는 방법이 있는데 이 방법은 생산 원가가 높아서 경제적이지 못하고 화학 생산의 특성 때문에 생산과정에서 여러 형태의 환경 오염을 초래하는 폐단과 석유자원 고갈의 문제점을 가지고 살아가고 있는 인류의 입장에서 에너지 해결의 난점에 봉착한 것이다.In addition, there is a method of extracting by using petroleum resources to generate hydrogen gas, which is not economical due to high production cost and problems of exhaustion and exhaustion of petroleum resources that cause various forms of environmental pollution in the production process due to the characteristics of chemical production. From the standpoint of human beings who live with their energy, they faced the difficulties of solving energy.

또 하나의 종래 문제점으로 대두되는 것은 화석 연료 사용으로 인한 환경오염과 석유자원 에너지 고갈을 해결하기 위하여, 조력, 조류, 파력, 풍력, 태양광의 친환경 재생에너지를 이용하여 발전하여 산업에 이용하려 노력을 많이 하지만 자연 환경에 영향을 받는 친환경 재생에너지는 24시간 꾸준히 에너지원이 제공되지 않아 발전 환경이 수시로 변하는 상황으로 전개되어 주 산업에 이용할수 없는 문제점이 있는 것이다Another conventional problem is to solve the environmental pollution and depletion of petroleum resources caused by the use of fossil fuels, and try to use it in the industry by using the renewable energy of tidal power, tidal current, wave power, wind power and solar power. However, the eco-friendly renewable energy affected by the natural environment is not available to the main industry because the power generation environment changes from time to time because the energy source is not provided steadily for 24 hours.

이러한 문제점을 내포하고 있는 친환경 재생 에너지의 문제점을 해결하여 주 산업에 이용하기 위하여 친환경 재생 에너지를 에너지원으로 하여 발전한 전기를 산업에 직접 송전하지 않고 자연 환경에 따라 발전할때 발생한 전류를 이용하여 해수를 현장에서 전기분해하여 수소를 발생시켜 연료전지 생산을 하고 연료전지를 탑재한 발전기를 이용하여 발전하여 주산업에 이용할수 있으며, 연료전지를 이용하여 자동차 등 동력원이 필요한 기계등에 탑재시켜 운전함으로써, 친환경 재생 에너지를 24시간 꾸준히 제공할수 있는 것이다In order to solve the problem of eco-friendly renewable energy, which contains these problems, it is possible to use seawater by using electric current generated when developing according to the natural environment without directly transmitting electricity generated by using eco-friendly renewable energy as an energy source to the industry. Can be used to produce fuel cells by generating hydrogen by electrolysis in the field, and generate power using a generator equipped with fuel cells for use in the main industry. We can provide green renewable energy for 24 hours
