Proton Exchange Membrane (PEM) fuel cell generates electrical energy by transforming chemical energy produced through an electrochemical reaction. These type of fuel cells are being considered for a wide variety of portable applications including automotives and cell phones. This tutorial introduces the user to the fuel cell modeling capability available in CFD-ACE+ through its flow, heat transfer, electric and electro-chemistry modules.

Solid Oxide Fuel Cells (SOFC) generates electrical energy by transforming chemical energy produced through an electrochemical reaction and are capable of operating at higher temperatures compared to other types of fuel cells.  A tubular SOFC is considered in this tutorial.

 

Turbulent mixing is important in a wide variety of applications. One such application is high speed air breathing aircraft engines (supersonic combustion/hypersonic aircrafts). As aircrafts continue to fly at higher speeds, complete mixing has to be achieved within shorter combustion chambers to minimize fuel consumption,  avoid combustion instabilities and decrease emissions. The turbulent mixing of two streams of gases (propane and air) is modeled in this tutorial.
