Simulation of Internal Manifold-Type Molten Carbonate Fuel Cells (MCFCs) with Different Operating Conditions

Molten carbonate fuel cells (MCFCs) use molten as an electrolyte. MCFCs operate at high temperatures and have the advantage of using methane a because they can nickel-based catalysts. We analyzed performance internal manifold-type MCFC, according to operating conditions, computational fluid dynamics. Different conditions were used for external reforming-type MCFCs. Flow directions, gas utilization, The S/C ratio reforming area A simulation model was developed, considering transfer, reaction, heat transfer. results showed similar pressure drops in all flow directions. As utilization decreased, temperature but increased. improved with increasing temperatures. that more hydrogen produced increased accordingly. More However, obtained when contained same active area. compared under conditions. efficiency is higher than
