*Separate Electric furnace and other system like Electronic scale
-Because Electric furnace temperature is very high
so we need to protect other system.

We have a tendency to think CO2 is negative. Because of Global warming. But, In other face, CO2 is very useful to use.
As you can see we use Co2 in various ways. For example, in our lives, we can see Co2 in beverages, and in concert, we see Co2 in form of gas.
Anyway, Today I explain to you about this, Electrochemical reaction. We convert Co2 to other materials using electrochemical reaction.
electrochemical device and therefore, there is no high-temperature step as normal burning. This direct conversion of chemical energy to electrical energy is more efficient and generates much less pollutions than do traditional methods that rely on combustion.
Fuel Cell Functionality
Fuel cells generate electricity from a simple electrochemical reaction in which an oxidizer, typically oxyge
반전지 전기화학반응(half-cell electrochemical reaction)이라고 부른다.
실제로 부식이 발생할 때 자유에너지 변화를 측정하기가 어려움으로 대신에 전기화학적 전위, E 를 측정한다.
반응의 전위는 양극반응과 음극반응의 각각 반전지전위의 합이다. 여기서 E 값이 + 이면 자유에너지는 -이고 자발적이다.
