This is how Gree
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.
