MATHEMATICAL ANALYSIS OF PLANAR SOLID OXIDE FUEL CELLS

摘要

Fuel cells are electrochemical devices that convert the chemical energy stored in a fuel directly into electrical power. The main attractive features of fuel cell systems are quiet operation and low emissions. However, some issues in reducing manufacturing and material costs, improving stack performances, their reliabilities and lifetimes, must be solved to enable commercialization. Solid Oxide Fuel Cell (SOFC) is considered as one of the most promising energy conversion device and as an alternative of existing power generation systems. SOFCs operate at high temperatures from 600°C to 1,000°C to ensure sufficient ion conductivity through their electrolytes which are nonconductive to electrons. Main SOFC components include air channel, cathode, electrolyte, anode, fuel channel, and interconnects.
