I was thinking more on the mechanism behind charging and discharging the capacitors on the TRIMET.

As I understand it, the TRIMET works by using the solar cells to charge the capacitor, and when the capacitor is at a certain voltage, the capacitor discharges into the motor.

I'm thinking of using a similar method, but in reverse. When the capacitor decreases to a certain voltage, it is sort of disconnected from the system, and the fuel cell is allowed to dominate.

You explained to me last year something about the drop out voltage. If I had that wired so that if the capacitor's voltage dropped below, the relay then connects the fuel cell to the motor?
