연료용 수소가스 공급장치 및 이를 포함하는 차량{DEVICE FOR SUPPLYING HYDROGEN GAS AS FUEL AND VEHICLE COMPRISING THE SAME}DEVICE FOR SUPPLYING HYDROGEN GAS AS FUEL AND VEHICLE COMPRISING THE SAME

본 발명은 내연기관 등의 연료로서의 수소가스(H2)를 제공하기 위한 수소가스 공급장치에 관한 것으로서, 보다 상세하게는 물의 전기분해를 통해 연료용 수소 및 산소를 생성 및 공급하는 장치 및 이를 포함하는 차량에 관한 것이다.The present invention relates to a hydrogen gas supply device for providing hydrogen gas (H 2 ) as fuel, such as an internal combustion engine, and more specifically, an apparatus for generating and supplying hydrogen and oxygen for fuel through electrolysis of water and the same It is about a vehicle to do.

본 발명과 같이 물을 전기분해하여 얻어지는 수소가스(H2)를 연료로서 사용하는 발명은 종래 다수의 기술에서 제안된 바 있다.The invention using hydrogen gas (H 2 ) obtained by electrolysis of water as a fuel as in the present invention has been proposed in a number of conventional techniques.

예를 들어, 특허등록 제10-0802748호 '연료전지 활성화를 위한 수소가스 및 산소 공급장치'(등록일자: 2008.02.01.)에서는 연료전지에서 발생되는 전력을 이용하여 물을 전기분해해서 생성된 수소가스와 산소를 다시 연료전지 스택을 활성화하는데 사용하는 기술을 제안하고 있으나, 이는 본 발명과 같이 수소가스 기체 자체를 연료로서 사용하기 위한 것이 아니라 연료전지를 활성화시키기 위한 것으로서 기본적으로는 연료전지로부터 발생되는 전기에너지를 이용하여 동력을 발생시키는 원리에 있어서는 본 발명과 크게 차이가 있다.For example, Patent Registration No. 10-0802748, 'Hydrogen gas and oxygen supply device for fuel cell activation' (registration date: 2008.02.01.), Was generated by electrolysis of water using electric power generated from a fuel cell. Although a technique is proposed to use hydrogen gas and oxygen to activate the fuel cell stack again, this is not to use the hydrogen gas gas itself as fuel as in the present invention, but to activate the fuel cell, and basically from the fuel cell. The principle of generating power using generated electrical energy is significantly different from the present invention.

또한, 특허등록 제10-0843064호 '수소가스/산소가스 혼합 대체연료'(등록일자: 2008.06.25.)에 개시된 발명은 물을 전기분해하여 얻어지는 수소가스/산소가스를 기존의 화석연료인 LNG, LPG 등에 혼합하여 대체연료로서 제공하고자 한 것으로서, 수소가스 가스를 분사연료와 혼합하여 사용하도록 하는 본 발명과 일부 공통점이 있기는 하나 물을 전기분해하여 수소가스를 공급하는 구체적인 방안이 제시된바 없이 화석연료와의 혼합비율만을 제시하고 있을 뿐이어서 본 발명과는 직접적인 관련성이 없다.In addition, the invention disclosed in Patent Registration No. 10-0843064 'Hydrogen gas / oxygen gas mixed alternative fuel' (registration date: 2008.06.25.) Is the existing fossil fuel LNG , Which is intended to be provided as an alternative fuel by mixing with LPG, etc. Although there is some similarity to the present invention in which hydrogen gas gas is mixed with injection fuel, a specific method of electrolyzing water to supply hydrogen gas is not suggested. It shows only the mixing ratio with fossil fuels, so it has no direct relationship with the present invention.

The supplied hydrogen gas is burned together by forming a mixture mixed with fossil fuel supplied from the fuel injector 2b.

본 실시예에서 수소가스는 화석연료와 별도의 경로를 통해 연소실린더(2a)로 공급되는 것으로 설명되었으나 본 발명이 이러한 방식에 한정되는 것은 아니며, 수소가스는 화석연료와 먼저 일정 비율로 혼합된 다음 그 혼합물이 연소실린더(2a)에 공급되도록 하는 방식을 취할 수도 있다.In this embodiment, the hydrogen gas is described as being supplied to the combustion cylinder 2a through a separate path from the fossil fuel, but the present invention is not limited to this method, and the hydrogen gas is first mixed with the fossil fuel at a certain ratio. It is also possible to take a method in which the mixture is supplied to the combustion cylinder 2a.

한편, 연소실린더(2a) 내 고온고압의 환경으로 인해 수소가스공급 관로(96)의 수소가스가 폭발하여 역방향으로 전달되는 것을 차단하기 위해, 도 1에 도시된 바와 같이 수소가스공급탱크(50)의 전,후 관로(94, 95)에는 역화방지구(103, 104)가 설치된다.On the other hand, due to the high temperature and high pressure environment in the combustion cylinder 2a, in order to prevent the hydrogen gas from the hydrogen gas supply pipeline 96 from being exploded and transmitted in the reverse direction, the hydrogen gas supply tank 50 as shown in FIG. Flashback prevention devices (103, 104) are installed in the front and rear pipelines (94, 95).

역화방지구(103, 104)는 관로(94, 95)를 통과하는 수소가스의 정상적인 온도범위를 초과하는 고온의 환경에서 해당 관로(94, 95)를 폐쇄하도록 거동하는 수단으로서 일반적으로 제안되고 있는 안전부품일 수도 있으며, 간단한 예를 들자면 밀랍으로 관을 형성하여 고온 발생시 상기 밀랍이 녹아 관을 폐쇄시키도록 하는 구성에 의할 수도 있다.Flashback prevention devices (103, 104) are generally proposed as a means to act to close the pipeline (94, 95) in a high temperature environment that exceeds the normal temperature range of hydrogen gas passing through the pipeline (94, 95). It may be a safety component, or, for example, may be formed by forming a tube with beeswax to melt the beeswax and close the tube when a high temperature occurs.

이러한 역화방지구는 제1 관로(92)와 제2 관로(93)에도 추가 설치함으로써 보다 확실한 안전을 도모할 수 있다.Such a backfire prevention device can further secure the safety by additionally installing the first pipeline 92 and the second pipeline 93.
