New Fuel Cell Power Plants Deployed in South Korea and California

How Solid-Oxide Fuel Cells WorkSouth Korea Is An Early Adopter of Fuel Cell TechnologyFuel Cell Servers Also Added in CaliforniaAccording to Bloom Energy, its “servers” convert fuel into electricity through an electrochemical process, without combustion, at the highest efficiency of any power solution available in the world today. The scheme has a modular design—any number of systems can be clustered together in various configurations to form solutions from hundreds of kilowatts to tens of megawatts. Solid-oxide fuel cells consist of three parts: an electrolyte, an anode electrode, and a cathode electrode. The electrolyte is what the electrical ions move through in a fuel cell. For a solid-oxide fuel cell, the electrolyte is a solid ceramic material. The anode and cathode are made from special inks that coat the electrolyte. Unlike other types of fuel cells, no precious metals, corrosive acids, or molten materials are required in the Bloom Energy design. An electrochemical reaction converts fuel and air into electricity without combustion. The system operates at high temperatures. Warmed air enters the catho...Get price
