How Fuel Cell Cars Work

How fuel cell cars work A fuel cell is a clean and efficient power plant that makes electricity through a chemical reaction between hydrogen and oxygen. Fuel port The tanks are refilled at hydrogen fueling stations. Power control unit Electric motor Propels the vehicle with little noise or Manages the fuel cell and the battery output and input in accordance with driving conditions. vibration. It can also recover energy during deceleration. Battery Power Hydrogen control unit Tanks Battery Stores energy recovered during deceleration and helps during acceleration. Fuel Cell stack Motor Safety measures Sensors shut the valves of the tanks in cases of High-pressure hydrogen tanks Provide hydrogen to the fuel cells. impact or leakage. Oxygen Inside the fuel cell stack Inside each cell, hydrogen passes through a negative electrode where a catalyst strips electrons from the atoms. The electrons Hundreds of individual Hydrogen fuel cells – each H2 flow from the negative to the positive electrode, generating electricity. Electrons and hydrogen atoms travel through an electrolyte membrane to reach the positive side, where they join with oxygen to become water. producing less than one volt – are assembled inside the stack to Negative electrode produce enough voltage for the motor. catalyst Water Polymer electrolyte membrane Positive electrode catalyst Source: Toyota Motor Corp.
