1, MCFC componentsThe research and development of MCFC began in 1950. During the subsequent century century century, in terms of electrode reactors, battery materials, battery stack design, many progress have been made, and the scale has been expanded, which has reached 100KW level a few years, and has reached 250 ~ 2000 kW.
2, electrode
2.1 anode
The anode of MCFC is Ni-Cr or Ni-Al alloy, and the purpose of 2% a 10% C: is to prevent sintering, the focus of research is to increase the performance of the electrode, and develop a sulfur-resistant anode material.
2.2 Cathode
The requirements of MCFC on the cathode are well electrically conductive, high structural strength, low solubility in molten carbonate. The current NIO cathode, conductivity and structural strength are suitable. Cathode dissolution is the main factor affecting the life of MCFC, especially when pressurized.
The possible way to solve the dissolution of the cathode is: developing new cathode materials, increasing the thickness of the substrate, increasing the additive in the electrolyte to increase its alkaline.

3. 1 vector
The carrier is a ceramic particle stick, forming a capillary network accommodating electrolyte. The carrier is a substrate electrolyte providing structure, but does not participate in the electrochemical process. The physical properties of the substrate are largely controlled by vector. The key to achieving high performance, high-life MCFC is the optimum distribution of molten carbonate electrolytes. Another aspect of the electrolyte structure improvement is its ability to block the gas.
3.2 electrolyte
The components of the electrolyte also affect the performance and life of the MCFC from several aspects. Manufacturing a gentle battery environment is conducive to mitigating the cathode dissolution. One of the channels is to add additives to the electrolyte to increase its alkaline, and a small amount of additive does not affect the battery performance but the battery performance can be reduced when the dose is increased.
4, single battery
One feature of the MCFC is to use the electrolyte tile (also known as substrate) by the carrier and carbonate. The electrolyte is fixed in the carrier. Electrolyte watts are both an ionic conductor, a yin, anode block, which can be used for gas sealing of batteries to prevent gas leakage.
5, battery stack
Simple repetition of the single battery structure constitutes a battery heap structure. The partition, also known as the bipolar plate, replaces the outer casing of the single battery. As the connection between the battery. If the electrons between the bipolar plates and the electrodes are sufficient, an electrode or bipolar current collector can be canceled. Both sides of the bipolar plate are made into corrugated, and the reactive gas is passed. The bipolar plate ripple is in contact with electrolysis, and a constant pressure is applied to reduce contact resistance. One of the main advantages of MCFC is that the battery area can be made large without large mechanical pressures. This is due to the plasticity of the electrolytic watt and the ductility of the metal bipolar plate.
