What are the solid oxide fuel cell components?

What are the solid oxide fuel cell components?   The solid oxide fuel cell is an electrochemical device that directly converts the chemical energy in the fuel into electrochemical devices, high efficiency, zero pollution, noise, and the like. It provides high quality power supplies for civil, trade, military and transportation, etc. The following is a member of a solid oxide fuel cell 1, component technology Due to the high operating temperature of SOFC, the material of the component constituting the battery is high, including chemical stability, conductivity, high temperature mechanical properties compatibility, and the like in the oxidative environment.   2, electrode 2.1 anode The electrode of SOFC is a microporous gas diffusion electrode. The anode is generally consisting of a metal nickel and an oxidative stable zinc oxide (YSZ) skeleton-ceramic alloy (a mixture of ceramics and metal). In numerous metal elements, metal nickel is due to its good electron conductivity and its stability under chemical reduction conditions, and nickel can also catalyze the internal reforming reaction, so that the reaction directly occurs directly on the electrode.   The role of YSZ is to prevent metal particles from sintering, and can make the anode coefficient to the coefficient of thermal expansion of other components of the battery.   2.2 Cathode Similar to the anode, the cathode is also a microporous structure so that the reactant gas and product gas have a high mass transfer speed. Most of the cathode materials are electron conductive oxides or a ceramic material for electron and ionic mixing conductive.   This is because this structure also has the conductivity of ions and electrons, and this is critical to low temperature SOFC. When the working temperature is about 650 ¡ã C, the advantages of using this mixed conductive oxide are obvious.   3, electrolyte SOFC requirements for electrolytes are as follows: (1) High oxygen ion conductivity; (2) low electronic conductivity; (3) Do not penetrate the reaction gas. The zinc oxide based electrolyte is suitable for SOFC, mainly due to its simple ion conductivity.   4, connector The connector is configured to implement the connection between adjacent cells. The connector of the plate fuel cell is a bipolar plate shape, generally using expensive chromium nickel iron (INCONEL), suitable for operating temperatures at 800-1000 ¡ã C battery stack. The advantage of low temperature SOFC is that inexpensive materials can be used.   Connectors in tubular design, preferably to select ceramic materials, but this material needs to be sintered at high temperatures (1625 `C), which is one of the large problems of SOFC in preparation. In addition, it is necessary to take care of chemical stability and mechanical properties between the components of the battery, and there is no reduction in the sintering of overhearted temperature Recommend: LiFePO4 Battery Manufacturer Energy storage battery Manufacturer Integrated machine energy storage battery series Manufacturer Lead lithium battery Manufacturer Outdoor Backup Battery Manufacturer Portable outdoor power supply Manufacturer Power battery Manufacturer Powerwall LiFePO4 Battery Manufacturer Battery rack Manufacturers Telecom LiFePO4 Battery Manufacturer Wall mounted battery storage Manufacturer China Lifepo4 Battery LiFePO4 Battery 48V 150AH LiFePO4 Battery 48V 100AH
