Q97. Which one of the following is the exhaust pipe emission from Fuel Cell Electric Vehicles, powered by hydrogen?
Detailed Solution
Fuel Cell Electric Vehicles (FCEVs) operate by converting hydrogen and oxygen into electricity through an electrochemical process, with water being the primary byproduct. In a hydrogen fuel cell, hydrogen gas reacts with oxygen from the air to produce electricity, which powers the vehicle's electric motor.
The only emission from the exhaust pipe of an FCEV is water vapor and warm air, making them zero-emission vehicles at the point of use. Hydrogen peroxide, hydronium, and oxygen are not the exhaust emissions.
This question tests knowledge of clean energy technologies and their environmental impact, a crucial area in the Environment & Ecology syllabus.
