I am at an engineering camp called SESEY at Oregon State University and we are experimenting with PEM fuel cell cars.

We have come to a problem on how to chemically stop the car at a desired length.  We are trying to research iodine clock reaction to see if there's some way to stop the reaction and halt the car.

If someone could explain the process of the iodine clock reaction and any info about it that would be helpful to stopping the fuel cell car.
