FUEL CELLS – SOLID OXIDE FUEL CELLS | Overview

A solid oxide fuel cell (SOFC) is an electrochemical device to directly convert the chemical energy of a fuel into electricity at temperatures from 500 to 1000 °C. The high operational temperature offers certain advantages over lower temperature fuel cells, notably fuel flexibility, and can use carbon monoxide as a fuel and not become poisoned by it. Solid oxide fuel cells operate at high overall efficiency because of the use of high-grade exhaust heat in ‘combined heat and power’ applications or in combined-cycle gas turbine applications. As a result, SOFCs have various applications over a wide range of power from milliwatts to megawatts. This article provides an overview of SOFCs.
