본 발명은 공기접촉방법을 이용한 연료전지의 연료냉각 제어장치에 관한 것으로서, 더욱 상세하게는 연료전지의 연료극으로부터 배출되는 70~80℃의 액체연료를 공기접촉방법에 의해 냉각시킨 상태로 연료탱크에 공급함으로서 연료탱크의 액체연료 등의 농도 등을 간편하게 조절하여 연료전지에 공급할 수 있는 공기접촉방법을 이용한 연료전지의 연료냉각 제어장치에 관한 것이다.The present invention relates to a fuel cooling control apparatus for a fuel cell using an air contact method, and more particularly, to a fuel tank in a state in which a liquid fuel of 70 to 80 ° C discharged from an anode of a fuel cell is cooled by an air contact method. The present invention relates to a fuel cooling control apparatus for a fuel cell using an air contact method that can be supplied to a fuel cell by simply adjusting the concentration of liquid fuel or the like in the fuel tank by supplying the same.

일반적으로 연료전지는 연료가 가지고 있는 화학에너지를 화학반응에 의하여 직접 전기 에너지로 바꾸는 장치이고, 연료가 공급되는 한 전기를 계속적으로 생성할 수 있는 일종의 발전장치이다. 이와 같은 연료전지 중 메탄올을 직접 연료로서 사용하는 연료전지(DMFC; Direct Methanol Fuel Cell)는 메탄올을 직접 셀의 연료극(anode)에 연료로서 공급하고 공기극(cathod)에 공급되는 산소와의 반응으로 전기를 생성하는 장치이고, 연료극으로는 아래와 같은 화학식 1과 같은 반응이 일어 나면서 전자가 생성되고, 그 전자는 이동경로에 따라 공기극으로 이동하여 화학식 2의 반응을 일으킨다.In general, a fuel cell is a device that converts chemical energy of a fuel directly into electrical energy by a chemical reaction, and is a kind of power generation device capable of continuously generating electricity as long as fuel is supplied. Among these fuel cells, a direct fuel cell (DMFC) using methanol as a direct fuel supplies methanol directly as a fuel to the anode of the cell and reacts with oxygen supplied to the cathode. Is a device for generating an electron, and as the fuel electrode generates a reaction as shown in Formula 1 below, the electron is moved to the cathode according to the movement path to cause the reaction of Formula 2.

[화학식 1][Formula 1]

CH3OH + H2O → CO2 + 6H + 6e- CH 3 OH + H 2 O → CO 2 + 6H + 6e -

[화학식 2][Formula 2]

3/2 O2 + 6H+ + 6e- → 3H20 3/2 O 2 + 6H + + 6e - → 3H 2 0

그리고, 메탄올을 연료극에 공급하는 방법으로는 액체상태의 메탄올을 펌프로 공급하거나, 상온으로 저절로 기화되는 성질을 이용하여 기화되는 메탄올이 자연스럽게 연료극으로 가도록 유도하는 방법이 있다.As a method of supplying methanol to the anode, there is a method of supplying liquid methanol to a pump or inducing a vaporized methanol to naturally go to the anode using a property of vaporizing itself at room temperature.

한편, 연료극에는 화학식 1과 같이 이산화탄소와 미반응된 메탄올의 혼합가스가 발생하고, 공기극에는 수분이 포함된 혼합가스가 발생한다.Meanwhile, a mixed gas of carbon dioxide and unreacted methanol is generated in the anode, and a mixed gas containing moisture is generated in the cathode.

DMFC는 연료가 되는 메탄올의 온도나 농도 등이 최적 조건을 유지하여야 발전효율이 우수하기 때문에, 연료전지의 연료극에 공급되는 메탄올의 농도를 측정하기 위해 연료탱크에 수용된 메탄올을 연료전지에 공급하는 배관에 메탄올의 농도를 측정할 수 있는 농도센서가 일반적으로 설치된다. 그리고 연료전지의 연료극으로부터 배출되는 미반응 메탄올은 재사용하기 위해 연료탱크로 배관을 통해 배출된다. 미반응 메탄올의 배출온도가 70~80℃로 고온이기 때문에 연료탱크에 수용된 메탄올 의 온도를 상승시켜 압력변화가 발생하여 농도센서에 의해 메탄올의 농도를 정확하기 측정할 수 없고, 이에 따라 정밀하게 농도가 조절된 메탄올이 연료전지에 공급되지 않기 때문에 발전효율이 일정하지 못하는 문제가 있다.Since DMFC has an excellent power generation efficiency when the temperature and concentration of methanol used as fuel are maintained at an optimum condition, the piping for supplying the methanol contained in the fuel tank to the fuel cell to measure the concentration of methanol supplied to the anode of the fuel cell Concentration sensors are usually installed in the chamber to measure the concentration of methanol. The unreacted methanol discharged from the fuel electrode of the fuel cell is discharged through a pipe to the fuel tank for reuse. Since the discharge temperature of unreacted methanol is high at 70 ~ 80 ℃, the pressure change occurs by increasing the temperature of methanol contained in the fuel tank, and the concentration sensor cannot accurately measure the concentration of methanol. Since the regulated methanol is not supplied to the fuel cell, there is a problem that power generation efficiency is not constant.

이와 같은 종래의 문제점을 해결하기 위한 본 발명은 연료전지의 발전효율을 일정하게 유지시킬 수 있도록 연료전지의 연료극으로부터 배출되는 70~80℃의 액체연료를 냉각시킬 수 있는 공기접촉방법을 이용한 연료전지의 연료냉각 제어장치를 제공함에 그 목적이 있다.The present invention for solving the conventional problems as described above is a fuel cell using an air contact method that can cool the liquid fuel of 70 ~ 80 ℃ discharged from the anode of the fuel cell to maintain a constant power generation efficiency of the fuel cell Its purpose is to provide a fuel cooling control device.
