Ok, I mulled it over a bit and came up with the following circuit. (See attachment)
The toggle switch on the right is meant simply to arm/disarm the car itself so I can't have a false start without first arming the car.
The two wires on the right lead to the charging station. The charging station is simply a battery pack with a regulated 3v going into the system in order to charge the fuel cell.
I wasn't sure where to put the normally closed momentary switch. I figured as close as possible to the motor was best. Is that necessary?
Other than that, I think I'm set. I used ExpressSCH for circuit (

One last thing. Is there anything wrong with this circuit? Will it perform as I want it to perform?
