SOFCteknologian

SOFCteknologian refers to Solid Oxide Fuel Cell technology. These fuel cells operate at high temperatures, typically between 600 and 1000 degrees Celsius. This high operating temperature allows for a variety of fuels to be used, including natural gas, biogas, and even some heavier hydrocarbons, which can be internally reformed within the cell. The primary components of a SOFC are a solid ceramic electrolyte, typically yttria-stabilized zirconia, sandwiched between a porous anode and a porous cathode. At the anode, the fuel is oxidized, producing electrons, protons, and carbon dioxide. At the cathode, oxygen ions from the air combine with these electrons and protons to form water. The movement of oxygen ions through the solid electrolyte completes the electrical circuit, generating electricity. A key advantage of SOFCteknologian is its high electrical efficiency, which can exceed 60%, and can be further improved in combined heat and power (CHP) systems. The high operating temperatures also allow for efficient heat recovery. Challenges include material durability and sealing at high temperatures, as well as the slow start-up time due to the need to reach operating temperature. Despite these challenges, SOFCteknologian is considered a promising technology for stationary power generation and for applications requiring high efficiency and fuel flexibility.
