본 발명은 연료전지의 스택 냉각 및 온수 공급장치에 관한 것으로, 특히 열 회수율이 향상되고 온수저장탱크측 순환펌프의 소모 동력이 감소하여 시스템 효율이 향상되는 연료전지의 스택 냉각 및 온수 공급장치에 관한 것이다.The present invention relates to a stack cooling and hot water supply apparatus of a fuel cell, and more particularly, to a stack cooling and hot water supply apparatus of a fuel cell, in which heat recovery rate is improved and power consumption of a circulation pump side of a hot water storage tank is reduced, thereby improving system efficiency. will be.

연료전지 시스템은 연료가스(수소포함)와 공기(산소포함)를 막전극조합체(MEA)에서 반응시켜 전기를 생산하는 것으로, 연료가스와 공기를 공급하기 위한 공급장치, 이들에 적당한 습도를 부여하기 위한 가습장치, 공급 전 적당한 온도를 가지도록 하는 가열장치, 연료가스와 공기를 공급받아 전기를 생산하는 스택(stack), 스택으로부터 생산된 직류를 사용 가능한 교류로 전환하는 전력변환장치(PCS) 등으로 구성된다.A fuel cell system generates electricity by reacting fuel gas (including hydrogen) and air (containing oxygen) in a membrane electrode assembly (MEA), and a supply device for supplying fuel gas and air, and providing appropriate humidity to them. Humidifier for heating, heating device to have proper temperature before supplying, stack for producing electricity by receiving fuel gas and air, power converter (PCS) for converting direct current from stack into usable AC, etc. It consists of.

그런데, 연료전지의 상기 스택에서는 전기 생산과 동시에 열과 물이 생성되는데, 상기 열을 방출하여 스택의 온도를 적정 범위에서 유지해주어야만 스택의 발전 성능이 양호한 상태로 유지됨은 물론 스택의 손상을 방지할 수 있게 된다.However, heat and water are generated in the stack of the fuel cell at the same time as electricity is produced. Only when the heat is released to maintain the stack temperature in a proper range, the power generation performance of the stack is maintained in a good state, and the stack is prevented from being damaged. It becomes possible.

따라서, 도 1에 도시된 바와 같이, 스택(1)과 열교환기(2), 그리고 열교환기(2)와 온수저장탱크(3)의 사이에 각각 냉각수순환라인(4)과 온수순환라인(5)을 형성하고, 이들 각 라인에 순환펌프(6,7)를 설치하여 스택(1)의 냉각수와 온수저장탱크(3)의 온수를 순환시켜 상기 열교환기(2)에서 상호 열교환시킴으로써 스택(1)의 냉각이 이루어짐과 더불어 온수저장탱크(3)내 온수의 온도가 상승할 수 있도록 되어 있었다.Accordingly, as shown in FIG. 1, the cooling water circulation line 4 and the hot water circulation line 5 between the stack 1, the heat exchanger 2, and the heat exchanger 2 and the hot water storage tank 3, respectively. ), A circulation pump (6, 7) is installed in each of these lines to circulate the cooling water of the stack (1) and the hot water of the hot water storage tank (3) to heat exchange with each other in the heat exchanger (2). In addition to cooling), the temperature of the hot water in the hot water storage tank (3) was to be increased.

그리고, 상기 온수저장탱크(3)에는 시수(city water)공급라인(8)이 연결되어 물을 보충 받을 수 있도록 되어 있으며, 상기 온수저장탱크(3)에 온수공급라인(9)이 연결되고 이에 보조보일러모듈(10)이 설치되어 온수를 용도에 알맞은 온도로 상 승시켜 공급할 수 있도록 되어 있었다.The hot water storage tank 3 is connected to a city water supply line 8 so that water can be replenished, and the hot water supply line 9 is connected to the hot water storage tank 3. Auxiliary boiler module (10) was installed to increase the supply of hot water to a temperature suitable for the purpose.

그런데, 상기의 종래 장치에서는 온수저장탱크(3)내 온수의 온도가 상승하여 스택(1) 냉각수와 온도가 비슷해지면 열교환기(2)에서의 열교환량이 저하되고, 또한 온수순환라인(5)에서 온수 순환 정도가 저하되기 때문에 상기 순환펌프(7)에 의한 강제 순환량을 증가시키기 위하여 순환펌프(7) 작동에 보다 많은 에너지가 소모되게 된다.However, in the above-described conventional apparatus, when the temperature of the hot water in the hot water storage tank 3 rises and the temperature is similar to that of the stack 1 cooling water, the amount of heat exchange in the heat exchanger 2 decreases, and in the hot water circulation line 5 Since the degree of hot water circulation decreases, more energy is consumed in the operation of the circulation pump 7 to increase the forced circulation amount by the circulation pump 7.

즉, 열교환기(2)에서의 열회수량이 줄어듦은 물론 순환펌프(7) 작동 에너지의 소비가 증가하므로 시스템의 효율이 저하되는 문제점이 있었다.That is, there is a problem that the efficiency of the system is lowered because the amount of heat recovery in the heat exchanger 2 is reduced, as well as the consumption of operating energy of the circulation pump 7 increases.

또한, 같은 이유에 의하여 스택 냉각수의 온도조절이 용이하지 않게 되므로 스택(1)의 온도조절도 용이하지 않게 되어 보다 효율적인 발전이 저해되는 문제점이 있었다.In addition, since the temperature control of the stack cooling water is not easy for the same reason, the temperature control of the stack 1 is not easy, and there is a problem that more efficient power generation is inhibited.

이에 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 열회수율이 향상되고 온수 순환펌프의 소비 동력이 증가되지 않게 되어 시스템 효율이 향상되고, 스택 냉각수 및 스택의 온도 조절이 용이하여 보다 효율적이 발전이 이루어질 수 있도록 된 연료전지의 스택 냉각 및 온수 공급장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, the heat recovery rate is improved and the power consumption of the hot water circulation pump is not increased, the system efficiency is improved, the stack cooling water and the temperature of the stack is easy to control more efficient It is an object of the present invention to provide a stack cooling and hot water supply device of a fuel cell in which this generation can be made.

상기 온수순환라인의 상기 제1열교환기 이전 부분과 상기 시수공급라인의 사이에 제2열교환기가 설치된 것을 특징으로 한다.A second heat exchanger is installed between the portion before the first heat exchanger of the hot water circulation line and the water supply line.

또한, 상기 온수순환라인에 상기 제2열교환기를 경유하지 않는 바이패스라인이 형성되고, 상기 바이패스라인의 분기지점에 쓰리웨이밸브가 설치된 것을 특징으로 한다.The bypass line may be formed in the hot water circulation line without passing through the second heat exchanger, and a three-way valve may be installed at a branch point of the bypass line.

따라서, 스택 냉각수와 열교환하는 온수순환라인내 온수의 온도차를 크게 할 수 있게 되어 열회수율이 향상되고, 또한 온수순환라인의 온수순환이 원활하게 이루어지므로 순환펌프 구동 동력의 소모가 증가하지 않게 되므로 시스템 효율이 향상된다.Therefore, it is possible to increase the temperature difference of the hot water in the hot water circulation line that heat exchanges with the stack cooling water, thereby improving the heat recovery rate, and also because the hot water circulation of the hot water circulation line is smoothly performed, the consumption of the circulating pump driving power is not increased. The efficiency is improved.

이하, 본 발명을 첨부된 예시도면을 참조하여 설명한다.Hereinafter, the present invention will be described with reference to the accompanying drawings.

도 2는 본 발명에 따른 연료전지의 스택 냉각 및 온수 공급장치의 구성도이 다.2 is a block diagram of a stack cooling and hot water supply apparatus of a fuel cell according to the present invention.

스택(1)은 열방출을 위하여 냉각수순환라인(4)을 구비하고, 온수저장탱크(3)는 온수 생성을 위해 온수순환라인(5)을 구비한다. 이들 각 라인은 제1열교환기(2)를 통과하면서 상호 열교환하여 냉각수는 열을 방출하고 온수는 열을 회수한다.The stack 1 has a cooling water circulation line 4 for heat dissipation, and the hot water storage tank 3 has a hot water circulation line 5 for generating hot water. Each of these lines passes through the first heat exchanger 2 to exchange heat with each other so that the cooling water releases heat and the hot water recovers heat.

따라서 저온의 냉각수에 의해 스택(1)의 냉각이 이루어지고, 열을 회수한 온수는 온수저장탱크(3)와 제1열교환기(11)를 반복 순환하면서 온도가 상승된다.Therefore, the stack 1 is cooled by low temperature cooling water, and the hot water recovered is repeatedly heated in the hot water storage tank 3 and the first heat exchanger 11 to increase in temperature.

또한, 상기 냉각수순환라인(4)과 온수순환라인(5)에는 각각 냉각수와 온수의 원활한 순환을 위하여 순환펌프(6,7)가 구비된다.In addition, the cooling water circulation line 4 and the hot water circulation line 5 are provided with circulation pumps 6 and 7 for smooth circulation of the cooling water and the hot water, respectively.

상기와 같이 데워진 온수는 온수저장탱크(3)에 연결된 온수공급라인(9)을 통해 사용처로 공급되며, 이때 온수공급라인(9)에 설치된 보조보일러모듈(10)을 통해 소정의 온도로 추가 가열할 수 있도록 되어 있다.The warmed water as described above is supplied to the place of use through the hot water supply line (9) connected to the hot water storage tank (3), at this time additional heating to a predetermined temperature through the auxiliary boiler module (10) installed in the hot water supply line (9). I can do it.

그리고, 상기 온수저장탱크(3)에는 시수공급라인(8)이 연결되어 온수가 공급됨에 따른 부족한 물을 보충할 수 있도록 되어 있다. 이때, 상기 시수공급라인(8)을 통한 물의 보충은 외부 시수의 공급압력을 이용하는 것이므로 별도의 펌프를 필요로 하지 않는다.In addition, the hot water storage tank 3 is connected to the water supply line 8 so as to replenish insufficient water as hot water is supplied. At this time, the replenishment of water through the water supply line 8 uses the supply pressure of the external water supply and thus does not require a separate pump.

상기와 같은 구조에 있어서, 본 발명은 상기 온수순환라인(5)과 상기 시수공급라인(8)의 사이에 또 다른 열교환기 즉, 제2열교환기(11)가 설치되어 이루어진다.In the above structure, another heat exchanger, that is, a second heat exchanger 11 is provided between the hot water circulation line 5 and the water supply line 8.

상기 제2열교환기(11)는 상기 온수순환라인(5)에 있어서 제1열교환기(2)의 이전 부분과 상기 시수공급라인(8)의 임의의 부분 사이에 설치되어, 온수순환라인 (5)의 온수가 고온부를 형성하고 시수공급라인(8)의 시수가 저온부를 형성하여 이들 고온부와 저온부 사이에 열교환이 이루어지도록 되어 있다.The second heat exchanger 11 is installed between the previous part of the first heat exchanger 2 and any part of the water supply line 8 in the hot water circulation line 5, thereby providing a hot water circulation line 5 The hot water of) forms a high temperature portion, and the time water of the water supply line 8 forms a low temperature portion so that heat exchange occurs between these high temperature portions and the low temperature portion.

따라서, 상기 온수저장탱크(3)로부터 제1열교환기(2)로 유입되는 온수는 상기 제2열교환기(11)를 통과하면서 자신보다 온도가 더 낮은 시수공급라인(8)의 시수와 열교환하게 되어 온수저장탱크(3)내에 있을 때 보다 낮은 온도를 갖게 된다.Therefore, the hot water flowing from the hot water storage tank 3 to the first heat exchanger 2 passes through the second heat exchanger 11 and exchanges heat with the time water of the water supply line 8 having a lower temperature than itself. It has a lower temperature than when it is in the hot water storage tank (3).

즉, 상기 제1열교환기(2)에는 종래보다 낮은 온도의 온수가 공급되는 바, 상기 냉각수순환라인(4)의 냉각수로부터 보다 많은 양의 열을 회수할 수 있게 된다.That is, the first heat exchanger (2) is supplied with hot water at a lower temperature than the conventional one, so that a greater amount of heat can be recovered from the cooling water of the cooling water circulation line (4).

또한, 상기와 같이 종래에 비하여 온도차가 크게 발생하므로 온수순환라인(5) 내의 온수순환이 원활하게 이루어지게 되며, 이에 따라 온수순환용 냉각펌프(7)를 보다 빠르게 가동시키기 위해서 전력의 소모가 증가하던 것을 방지할 수 있게 되었다.In addition, since a large temperature difference occurs as described above, hot water circulation in the hot water circulation line 5 is smoothly performed, and accordingly, power consumption is increased to operate the hot water circulation cooling pump 7 more quickly. You can prevent that.

즉, 본 발명에 따르면, 상기와 같이 온수에 의한 스택 냉각수로부터의 열회수율이 증가하고 또한 온수를 순환시키는데 소모되는 동력 증가분이 감소하게 되므로 시스템의 효율이 증가하게 된다.That is, according to the present invention, the heat recovery rate from the stack cooling water by hot water is increased as described above, and the power increase consumed in circulating the hot water is reduced, thereby increasing the efficiency of the system.

또한, 상기와 같이 냉각펌프(7)를 보다 빠르게 작동시킬 필요가 없어지게 되므로 냉각펌프(7)를 보다 작은 용량의 것으로 대체하여 경비를 절감할 수도 있게 된다.In addition, since it is not necessary to operate the cooling pump 7 faster as described above, it is possible to reduce the cost by replacing the cooling pump 7 with a smaller capacity.

또한, 종래에는 스택 냉각수의 온도에 영향을 미치는 요소가 상기 온수순환라인(5)의 온수에 한정되어 있었으나, 본 발명에 따르면 시수공급라인(8)의 시수가 스택 냉각수의 온도에 영향을 미치는 또 다른 요소로서 작용하게 되므로 스택 냉각 수의 온도제어가 보다 용이하게 된다.In addition, in the related art, the factor affecting the temperature of the stack cooling water was limited to the hot water of the hot water circulation line 5, but according to the present invention, the time of the water supply line 8 affects the temperature of the stack cooling water. By acting as another factor, temperature control of the stack cooling water becomes easier.

한편, 상기 온수저장탱크(3) 내의 온수 온도가 과도하게 상승되지 않아 제1열교환기(2)로 공급되는 온수의 온도를 낮출 필요가 없을 경우에는 온수순환라인(5)의 온수를 상기와 같이 제2열교환기(11)를 경유하지 않고 직접 제1열교환기(2)로 공급하는 것이 필요하게 된다.On the other hand, if the hot water temperature in the hot water storage tank (3) does not increase excessively so that it is not necessary to lower the temperature of the hot water supplied to the first heat exchanger (2) the hot water in the hot water circulation line (5) as described above It is necessary to supply directly to the first heat exchanger 2 without passing through the second heat exchanger 11.

이를 위하여 도 3에 도시된 바와 같이, 상기 온수순환라인(5)에는 제2열교환기(11)의 이전/이후 부분을 연결하여 온수가 제2열교환기(11)의 이전부분으로부터 상기 제1열교환기(2)쪽으로 직접 흐르도록 하는 바이패스라인(12)을 형성한다.To this end, as shown in FIG. 3, the hot water circulation line 5 is connected to a before / after part of the second heat exchanger 11 so that hot water is transferred from the first part of the second heat exchanger 11 to the first heat exchanger. A bypass line 12 is formed to flow directly toward the machine 2.

그리고, 상기 바이패스라인(12)의 시작지점 즉, 온수순환라인(5)에서 상기 바이패스라인(12)과 제2열교환기(11)로의 유입라인의 분기지점에 쓰리웨이밸브(13)가 설치된다.In addition, a three-way valve 13 is formed at a start point of the bypass line 12, that is, at a branch point of an inflow line from the hot water circulation line 5 to the bypass line 12 and the second heat exchanger 11. Is installed.

따라서, 상기 쓰리웨이밸브(13)의 전환상태에 따라 온수의 유로는 온수저장탱크(3)로부터 제2열교환기(11)를 거쳐 제1열교환기(2)로 유입되는 라인과, 온수저장탱크(3)로부터 제2열교환기(11)를 거치지 않고 제1열교환기(2)로 직접 유입되는 라인의 2가지가 존재하게 된다.Therefore, according to the switching state of the three-way valve 13, the flow path of hot water flows from the hot water storage tank 3 to the first heat exchanger 2 via the second heat exchanger 11, and the hot water storage tank. There are two types of lines directly flowing from (3) to the first heat exchanger 2 without passing through the second heat exchanger 11.

따라서, 제1열교환기(2)로 공급되는 온수의 온도를 보다 용이하게 제어할 수 있게 되어 스택 냉각수의 온도제어가 용이해지고, 이로써 스택(1)의 냉각정도를 용이하게 조절할 수 있게 됨으로써 결국 스택(1)의 온도를 적정 범위에서 유지하기 용이해짐으로써 스택(1)이 항상 최적의 발전성능을 발휘할 수 있게 된다.Therefore, the temperature of the hot water supplied to the first heat exchanger 2 can be more easily controlled, thereby facilitating the temperature control of the stack cooling water, thereby making it possible to easily control the degree of cooling of the stack 1, and thus the stack. By maintaining the temperature of (1) within an appropriate range, the stack 1 can always exhibit the optimal power generation performance.

이상 설명한 바와 같이 본 발명에 따르면, 시수를 이용하여 스택냉각수와 열교환하는 온수의 온도를 낮출 수 있게 됨으로써 스택의 냉각성능 및 시스템의 열회수율이 향상된다. 그리고, 온수의 순환효율이 향상되어 온수순환용 펌프의 소비 동력이 감소하므로 시스템의 효율이 향상되는 효과가 있다.As described above, according to the present invention, it is possible to lower the temperature of the hot water heat-exchanging with the stack cooling water using time water, thereby improving the cooling performance of the stack and the heat recovery rate of the system. In addition, since the circulation efficiency of the hot water is improved, the power consumption of the hot water circulation pump is reduced, thereby improving the efficiency of the system.

또한, 상기와 같이 온수가 원활하게 순환됨으로써 대용량의 순환펌프가 필요없게 되므로 작은 용량의 순환펌프로 대체가 가능하게 되어 비용을 절감할 수 있게 된다.In addition, since the hot water is smoothly circulated as described above, a large capacity circulating pump is not required, thereby enabling a replacement of a small capacity circulating pump, thereby reducing costs.

또한, 스택 냉각수의 온도에 영향을 미치는 요소로서 시수가 추가되고, 이 시수에 의한 영향을 선택적으로 적용할 수 있음으로써 스택 냉각수의 온도를 보다 용이하게 제어하여 스택의 발전성능을 향상시킬 수 있게 된다.In addition, time is added as a factor that affects the temperature of the stack coolant, and the influence of the time can be selectively applied to improve the stack power generation performance by more easily controlling the temperature of the stack coolant. .
