What is SOFC technology?
What is SOFC technology?
A solid oxide fuel cell (or SOFC) is an electrochemical conversion device that produces electricity directly from oxidizing a fuel. Fuel cells are characterized by their electrolyte material; the SOFC has a solid oxide or ceramic electrolyte.
How an SOFC works?
The basic structure of an SOFC consists of a solid electrolyte (usually a ceramic) positioned between an anode and a cathode. Fuel is delivered to the anode and oxidant, typically air, is delivered to the cathode. Fuel diffuses through the anode to the anode/electrolyte interface.
What is the difference between Sofcs and PEM based fuel cells?
PEMFC is compact and handles generally load variations better. SOFC is not as compact and works at higher temperatures than PEMFC. The SOFC can be combined with a gas turbine increasing its efficiency. If waste heat recovery is used its efficiency is further increased.
Which of these is the best definition of a fuel cell?
Which of these is the best definition of a fuel cell? a voltaic cell that uses the oxidation of a fuel to produce electricity.
What are SOFC used for?
SOFCs are well suited to stationary power generation for homes and businesses. Their high temperatures make them particularly efficient for Combined Heat and Power (CHP) systems, as waste heat can be put to good use for heating and cooling.
What are the four main parts of a PEMFC?
PEMFCs are built out of membrane electrode assemblies (MEA) which include the electrodes, electrolyte, catalyst, and gas diffusion layers.
Who has the best fuel cell technology?
Key Points. Hyundai and Toyota are the dominant players in the fuel cell electric vehicle market. The two companies are investing in advancing fuel cell technology.

What does an electrolyzer do?
An electrolyzer is a system that uses electricity to break water into hydrogen and oxygen in a process called electrolysis. Through electrolysis, the electrolyzer system creates hydrogen gas.
What is the range of working temperature of SOFC?
between 550 and 1000 °C
The operational temperature of SOFC membrane ranges between 550 and 1000 °C depending on the electrolyte type and thickness as well as electrodes used.
SOFC technology is inherently modular and fuel flexible. Thus cell and stack designs demonstrated at the bench scale can directly be scaled and aggregated into modules that serve as the building blocks for utility-scale SOFC power systems. THE PROGRAM
How many projects are in the SOFC program?
The SOFC program maintains a diversified portfolio of more than 20 short-, mid -, and long-term R&D projects N EX T ECH M ATERIALS EX ANL
What are the key determinants of SOFC power systems?
Cell Technology—The electrochemical performance, durability, and reliability of the solid oxide fuel cell are the key determinants in establishing the technical and economic viability of SOFC power systems. The components of the KEY TECHNOLOGIES
What is Fe SOFC program mission?
6 FE SOFC Program Mission Enable the generation of efficient, low-cost electricity from domestic coal and natural gas with near- zero emissions of CO 2 and air pollutants and minimal use of water in central power generation applications. Increase reliability, robustness, and durability of cell and stack technology.
