With different types of electric vehicles differ slightly. Only equipment in pure electric vehicle battery, the battery is the only power source for the role of automotive drive systems. In conventional engines and equipment (or fuel cell) and hybrid electric vehicle battery, the battery can play a major power source for automotive drive system role, but also act as an auxiliary power source. Visible at low speeds and start playing the role of a battery vehicle drive system of the main power source; at full load when accelerating car battery manufacturers, to act as the role of an auxiliary power source; in normal driving or deceleration, braking act is the role of energy storage. Role of the fuel cell anode is to provide a common interface for the fuel and electrolyte, and a catalyst for oxidation of fuel, while the electron transport produced in the reaction to an external circuit or the first current collecting plate and then transferred to the outward transmission circuit. Cathode (oxygen electrode) is to provide a common interface for oxygen and Dongguan car battery electrolyte, a catalyst for oxygen reduction, transfer of electrons from the external circuit to the oxygen electrode reaction site. Since the reaction occurs mostly on the electrode interface reaction multiphase car battery, to increase the reaction rate, the electrodes are generally coated with a porous material and electro-catalyst. Role of ions in the electrolyte is produced by the electrode reaction in the fuel electrode and the oxygen electrode delivery, and to prevent the electron transfer between the electrodes directly.
