Difference between fuel cell and battery is given bellow:                           Battery                                   Fuel Cell 1)     Battery is a close system. Fuel cell is open system. 2)     Chemical Changes occurs There is no change in chemical composition of electrolyte. 3)     Fuel supply intermittent. Fuel supply continuous. 4)     No isothermal reaction inside. Isothermal reaction inside. 5)     Supply power for definite length of time. Fuel cell supply power for indefinite length of time.  

What is Battery? Definition of Battery : It is a device consist of one or more electro-chemical cell and it is used to convert stored energy in chemical form to electrical energy . One battery contain two types of cell One is primary cell and another is secondary cell. What is the  function of Battery ? Function of Battery:  There are three function one battery and they are given bellow: 1.      Engine Off: Battery energy is used to operate lighting and after accessory system. 2.      Engine Starting: Battery energy is used to operate the starter motor and provide current for ignition system during cranking.  3.      Engine Running: Battery energy is used when automobile electrical load exceed the supply from the charging system. Electrical System: 1.      Battery 2.      Starting System 3.      Charging System 4.      Ignition System
