What is a Hydrogen Fuel Vehicle?
1 Answers
Hydrogen fuel vehicles refer to automobiles that primarily use hydrogen as their energy source for propulsion. In conventional internal combustion engines, diesel or gasoline is typically injected, whereas hydrogen vehicles utilize gaseous hydrogen instead. Fuel cells and electric motors replace the standard engine. The principle of hydrogen fuel cells involves introducing hydrogen into the fuel cell, where the electrons of hydrogen atoms are blocked by a proton exchange membrane, then conducted through an external circuit from the negative to the positive electrode, generating electricity to drive the motor. Additional Information: 1. Hydrogen Fuel Principle: Hydrogen molecules combine with oxygen molecules through combustion to produce thermal energy and water. Hydrogen fuel cells generate electricity by combining liquid hydrogen with oxygen from the air. Based on this principle, hydrogen fuel cells can generate electricity to power vehicles, supply household or industrial electricity, or serve as mobile phone batteries. 2. Hydrogen Storage Methods: There are two traditional hydrogen storage methods. One method involves using high-pressure cylinders (hydrogen tanks) to store hydrogen, but these cylinders have limited storage capacity and pose explosion risks. The other method involves storing liquid hydrogen, but the storage tanks are very large and require excellent insulation devices to maintain temperature.
