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.
Experimental Setup

alternative energy
Hydrogen is one of well-known clean energy source.
Several technologies are already available in the marketplace for the industrial production of hydrogen.
Hydrogen can be produced from a variety of feedstocks.

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
Pros- Unlike regular fuel cell, MBFC can make energy in very mild condition.- MBFC can produce energy by consume variety organics.
Cons- MBFC need electrochemical mediator this mediator generally not degradable and very poisonous. so mediator can make 2nd pollution.- Output is low and unstable compared to general fuel cell.
The need for MBFC
