What fuel is used in hydrogen-powered car engines?
1 Answers
Hydrogen-powered car engines actually come in two types: hydrogen-fueled engines and fuel cell engines. Engines that use pure hydrogen fuel or hydrogen-blended fuel both belong to the hydrogen-fueled engine category. By making corresponding modifications to current gasoline engines, they can be adapted to burn hydrogen, offering strong practicality. Moreover, hydrogen can either premix with air before entering the cylinder or be directly injected into the cylinder to form a combustible mixture. The other type, fuel cell engines, primarily consist of components such as the fuel cell stack, engine controller, hydrogen supply system, and air supply system. Their core lies in the fuel cell engine system, which is crucial for the vehicle's operational safety and significantly impacts whether fuel cell vehicles demonstrate mature and reliable performance. Hydrogen-fueled cars use hydrogen as their primary energy source for propulsion. The greatest advantage of using hydrogen as an energy source is its reaction with oxygen in the air, producing water vapor as exhaust, effectively reducing the air pollution issues caused by traditional gasoline-powered vehicles.
