Our 2011-2012 car design will utilize a Proton Exchange Membrane (PEM) Hydrogen Fuel Cell Stack to supply power to a small electric motor.  Hydrogen and oxygen are supplied to each of our five fuel cells.  The anode breaks hydrogen down into a proton and an electron.  The PEM allows the proton to pass through while forcing the electrons to travel outside of the cell.  A small tank on the car will supply enough hydrogen to the hydrogen fuel cell to run the car for at least two minutes.


Our design will rely on an iodine clock reaction to obtain the desired distance.  This unique reaction starts by mixing two clear solutions together. 


         3 I-(aq) + H202 + 2 H+ (aq) = I3- (aq) + 2 H20 (l)

       I3- (aq)  +  2 S2O3 2- (aq) =  3 I- (aq)  +  S4O6 2- (aq)

       2 I3- (aq) + starch  =  starch-I5- complex  +  I- (aq)


The solution suddenly turns a dark blue color at a certain time.  By changing the concentration of the hydrogen peroxide we can control the timing of our iodine clock reaction.  A photo resistor on one side of the reaction vessel will sense when the solution turns dark by reading the amount of light that passes through the vessel.  Once the sensor no longer detects light, it will cause our car to quit running.

Text Box: There are many challenges and obstacles the ChE Car team will have to overcome to develop this design into a working vehicle that can accurately achieve a range of distances with different amounts of liquid weight.    We have a large group of motivated members this year who are anxious to solve some of these difficult engineering problems.
