Motor for hydrogen fuel cell car.?

I am the head of the Chemical Engineering ChemE-Car team at my university. We are building a car that will be powered by a stack of Hydrogen Fuel Cells that output a constant 14 Volts. I have been trying to purchase an electric motor, but I am having trouble knowing where to go to find them. We need the motor to have a max current rating of 4 amps and a torque level of at least 2.45 Nm. If you could link me to a website that has such motors that would be great! (as a size reference, our car is a little bigger than a shoe box).
