Explanation
An electrochemical energy conversion device that directly converts chemical energy into electrical energy. The fuel used is stored in a storage tank outside the electrochemical reactor. The fuel cell has the following characteristics: ① the conversion from chemical energy to electric energy is completed at one time; ② the energy conversion is completed through the electrochemical process rather than the combustion process; ③ The reactants are stored outside the reactor; ④ It is an energy conversion device rather than an energy storage device.
