Solid Oxide Fuel Cell belong to the family of high-temperature fuel cells, operating typically in the range of 600 to 1000 degrees Celsius. Unlike traditional fuel cells that use liquid electrolytes, SOFC utilize a solid oxide, typically a ceramic material, as an electrolyte. This unique characteristic allows them to achieve higher efficiencies and versatility in fuel sources.

How do Solid Oxide Fuel Cell (SOFC) work?

SOFC operate on the principle of electrochemical conversion of fuel into electricity. Here's a simplified breakdown of the process:

Fuel Oxidation at Anode:

At the anode (negative electrode), fuel such as hydrogen, natural gas, or other hydrocarbons is introduced.

The fuel undergoes oxidation, releasing electrons and generating ions in the process.

Ion Migration through Electrolyte:

The generated ions move through the solid oxide electrolyte towards the cathode (positive electrode).

Electron Flow and Electricity Generation:

Simultaneously, the released electrons travel through an external circuit, creating an electric current.

At the cathode, oxygen from the air reacts with the electrons and migrating ions, producing water as a byproduct.
