One thought on “Would hydrogen fuel cell or photovoltaic cell would be a better alternative to power an electric automobile?”

————–
Hydrogen is impractical, since large amounts of electricity is required to extract it, and the efficiency of the fuel suffers in the process. Considering this, it makes more sense just to use that same electricity to power the vehicle, via an efficient battery.
*
Charging that same battery with photocells is the better answer of the two. While you can not get enough energy from a solar panel small enough to mount on the car itself, it is practical to charge EV batteries from larger panels mounted on a garage roof, and electric vehicle hobbyists are doing this today.
