M-COG Technology
M-COG stands for “Medical Ceramic Oxygen Generator”. Oxygen is separated through ionization and electrochemical processes. The output is 99.995+% oxygen.
What is a Medical Ceramic Oxygen Generator?
M-COG concentrators use an electrochemically active electrolyte (sometimes referred to as a ‘membrane’) in a construction which allows only oxygen ions to cross, in one direction only. Once across the ‘membrane’, the ions recombine to diatomic oxygen and can be accumulated. This accumulation has the side effect of building pressure, so no compressor or pumps are required.
Ceramic
An M-COG cell is comprised of multiple ceramic wafers. Each wafer has four layers: a substrate or ‘stongback’, a porous anode layer in which the oxygen can accumulate and through which it will flow to the outlet, the electrolyte or ‘membrane’ layer and an outer porous layer which is wired as the cathode.
Oxygen
Air is heated to cause the oxygen to disassociate into oxygen ions. These pass over the outer porous cathode layer. As the cathode and anode are energized, they pull the ions through the electrolyte layer into the porous anode layer. Once in the anode layer, the ions recombine to diatomic oxygen (02). The electrolyte is specific to oxygen, so no other molecule can cross.
Concentrator
As the oxygen molecules accumulate in the anode layer, they will produce pressure there. Having nowhere to escape except the oxygen outlet, they will flow out that outlet at the pressure desired, limited only by the mechanical strength of the wafer's construction.
