The fuel cell is mainly composed of three anode, cathode, and electrolyte. According to the electrolyte used, the fuel cell can be divided into: proton exchange membrane fuel cell (PEMFC), alkaline fuel cell (AFC), phosphate battery, molten carbonate fuel cell (MCFC), and solid oxide Five categories of fuel cells (SOFC).The key material of the solid oxide fuel cell has an anode, a cathode, an electrolyte, a sealing material, and a connection material, and the like. The traditional solid oxide fuel cell operates at a higher temperature, which has caused high materials for battery support, and difficulties in battery sealing. The electrolyte material is the core of the entire solid oxide fuel cell, the operating temperature of the fuel cell, the output power, and the like are directly affected; and the matching connection material and the electrode material are also limited by the electrolyte material, that is, the electrode of the solid oxide fuel cell. And its auxiliary materials must be prepared and designed around the electrolyte material. Solid Oxide Fuel Cell, referred to as SOFC, is suitable for large power plants and industrial applications.
SOFC has the highest working in all fuel cells. At such a high temperature, the fuel can be rapidly oxidized and reach thermodynamic balance. No precious metal catalyst can be used. SOFC is a full solid-state device, which is used as an oxide ion conductive ceramic material, which is simpler than other fuel cells in that it is only two-phase (solid phase and gas phase), and does not maintain the three-phase interface. There is no drowning electrode micropore. , Polar catalysts and other problems, no strict electrolyte management is required like PAFC and MCFC.
The oxide electrolyte is very stable, and there is no problem in the loss of electrolyte in MCFC, and its composition is not affected by fuel and oxidative gas components. SOFC can withstand overload, low load, or even short circuits.
Like MCFC, SOFC is also used as hydrogen and carbon monoxide gas, and fuel refines in the battery. Since the SOFC operating temperature, its ability to withstand sulfide is at least two orders of magnitude higher than other M battery cells, so that high temperature sulfur sulfur can be used, which is advantageous for energy saving.
In addition, the solid oxide electrolyte gas is low. Small electrical conductivity, and the SOFC voltage can be less than the theoretical value when the opening is opened. Compared to MCFC, the internal resistance loss of SOFC is small, and can operate under conditions with high current density. The fuel utilization is high, and the CO2 cycle is not required, so the system is simpler. The advantage of SOFC is high efficiency than other power generation technologies.
Disadvantages: One disadvantage of SOFC is free energy loss than MCFC, and its open circuit is 100 mV lower than MCFC. Therefore, unless the polarization and ohm loss are quite low,
The SOFC has a low power generation than MCFC, which is generally 6%, but this part of the efficiency loss can be compensated by the high quality of SOFC. In addition, since the operating temperature is high, SOFC has high requirements for materials.
