Are hydrogen fuel cells and solar panels allowed to power the electric vehicle?

Are hydrogen fuel cells and solar panels allowed to power the electric vehicle?

No to solar panels since by rule 2.b. the energy is not stored in the "battery. No, to hydrogen fuel cells since as far as we can tell there are no "common, commercially available" H fuel cells.

At a tournament I was told that because the axles of my vehicle did not fit the specified 30cm x 60cm space, I was given a construction violation even though the wheels/treads fit in the space. Is my vehicle legal in this configuration?

2.f. clearly says the wheels/treads must fit within the dimensions. Axles aren't mentioned and don't impact the measurements.

Clearly batteries must be less than 9V, but can we use step-up regulator to generate 12 V?

No, the voltage across any two points ≤ 9 V as stated by the manufacturer labels. If a step-up regulator steps a 9V battery up to 12V, this would be a violation.

How is "leading part of the vehicle" defined? Is it the forward-most part in the direction of the vehicle's travel or the closest part to the Target Point?

The "leading part of the vehicle" is the forward-most part in the direction of the vehicle's travel.

Is "backwards" motion any motion with a component in the direction of a vector starting at the finish and pointing toward the start, or is "backwards" a different direction?

Backwards motion is motion of the overall vehicle in the general direction opposite to the primary direction of travel during the run. If the vehicle is moving away from the start it is moving "forward" if the vehicle is moving towards the start then it is moving "backwards".

Is the bonus awarded if the vehicle moves one or both of the cans, but still passes between them? With 'move' defined as the distance between the cans after the run differs from the distance prior to the run, to the nearest 0.1 cm.

Yes, as long as the bonus requirements outlined in 3.c. are met, the bonus will be awarded. It is awarded based upon the initial distance between the cans.

Is the vehicle permitted to be propelled backwards outside of the run time (as defined in 5k)?

No. The rule is clear. ...please see rule 5.g.

What must fit within the 30.0x60.0cm rectangle? Simply the wheelbase where the treads touch the floor or the entirety of the wheels and treads, e.g. front edge of front wheel to the rear edge of the rear wheel?

"The wheels/treads in the ready-to-run configuration must fit in a 30.0 x 60.0 cm space of any height" means that the entirety of the wheels and treads (front edge of front wheel to the rear edge of the rear wheel) in the ready-to-run configuration must fit in a 30.0 x 60.0 cm space of any height.

When is this distance measurement taken? If a vehicle crosses the 8.5 m line, stops (no visible forward motion) for > 1 s, then begins moving again toward the target, then stops permanently - is the distance measurement take from the 1st or 2nd stop?

Distance measurement is taken when the vehicle stops permanently.

When it says that the vehicle cannot be propelled backward, does that apply to recoil which occurs when a vehicle stops, specifically if the vehicle moves backwards despite the actual propulsion only being forwards?

No, the minor recoil when a vehicle stops is not considered backwards propulsion. Ultimately it will be up to the event supervisor to determine if this movement was intentional to gain a benefit to the team.
