A solid oxide fuel cell (SOFC) is a type of fuel cell that uses a solid oxide electrolyte to convert chemical energy from a fuel into electrical energy. The SOFC is made up of two electrodes, an anode and a cathode, which are separated by a solid oxide electrolyte. The fuel, typically a hydrocarbon, is injected into the anode where it is oxidized and releases electrons, which then travel through an external circuit to the cathode. At the cathode, the electrons react with oxygen to produce water and heat. The heat released can be used to provide energy for other processes.
