Experts compare fuel cells with batteries but there is a great difference. The fact is batteries go down but the fuel cells don’t. The fuel cells are able to produce the needed car energy through a process called electrolysis. You can find 2 electrodes and 1 electrolyte in a fuel cell. The oxygen and hydrogen will be separated and after the whole process, heat and water will be produced.
