Engineers have designed a hydrogen fuel cell car which is powered by the energy that is released when hydrogen and oxygen combine. To do this, the car's engine transforms chemical energy into mechanical energy. The only substance released from these cars is water vapor. A student claims that cars powered by this type of fuel have an advantage over cars powered by gasoline. Which statement supports the student's claim?
Hydrogen fuel cell cars do not contribute to air pollution because their only exhaust is water.
Hydrogen fuel cell cars do not require maintenance like gasoline powered cars do.
Hydrogen fuel cell cars use non-renewable energy sources.
Hydrogen fuel cell cars can be designed in a variety of shapes.
