Fuel cells are electrochemical devices that convert chemical energy from the reactants directly into electricity and heat. The device consists of an electrolyte layer in contact with a porous anode and cathode on either side. An illustration of a fuel cell with reactant/product gasses and the ion conduction flow directions through the cell is...
Fuel cells have been researched and developed for use in several applications since the early 1990's. Fuel cells can be used for portable, backup, transportation, and stationary power applications. This article briefly describes some of these uses for fuel cells.
Gas Diffusion Layers (GDL) are one of the components in different types of fuel cells including, but not limited, to Proton Exchange Membrane and Direct Methanol fuel cells. Gas Diffusion Layers serve to provide conductivity in the cell and control the contact between the reactant gases and the catalyst. This layer also aids in managing the water transport out of the membrane. Another essential function of a GDL is to provide a connection between the membrane electrode assembly and graphite plates in the fuel cell stack.
The first Columbia Chemical Engineering Fuel Cell Car Demonstration and Competition was planned, developed, and executed in order to inspire and educate young people about chemical engineering. This hands-on experience was modelled after the American Institute of Chemical Engineers (AIChE) ChemE Car Competition using the X7 Fuel Cell Car....
