Electrical energy can be converted back into kinetic energy in electric motors: this happens with the windscreen wipers and the starter motor. Electrical energy is converted into light energy in the headlights. In fact the only kind of energy which you will not find in your car is nuclear energy.
A fuel cell is an electrochemical cell that converts the chemical energy from a fuel into electricity through an electrochemical reaction of hydrogen fuel with oxygen or another oxidizing agent. Fuel cells are different from batteries in requiring a continuous source of fuel and oxygen to sustain the chemical reaction, whereas in a battery the chemical energy comes from chemicals already present in the battery. Fuel cells can produce electricity continuously for as long as fuel and oxygen are su
