Sustainable transport
Fuel Cell Electric Vehicle (FCEV)
Definition
A fuel cell electric vehicle is a zero-emission electric vehicle powered by electricity produced onboard through an electrochemical reaction between stored hydrogen and oxygen from the air in a fuel cell stack. Because it produces no tailpipe emissions other than water and heat, and refuels in minutes, the technology is considered especially suitable for heavy-duty transport where battery weight and charging time are constraints.

Overview
What it means
FCEVs are electric drivetrains with a different energy source: instead of a large battery charged from the grid, they carry compressed hydrogen. Their climate benefit depends on how the hydrogen is produced — green hydrogen from renewable electricity offers deep cuts, while grey hydrogen from unabated natural gas shifts emissions upstream.
How it is used
The term distinguishes hydrogen vehicles from battery electric vehicles in policy incentives, zero-emission-vehicle mandates, and fleet decarbonisation strategies, particularly for trucks, buses, and material-handling equipment.
Why it matters
FCEVs are one of the few zero-emission options for long-haul and high-utilisation transport, and their rollout drives demand for low-carbon hydrogen infrastructure. **Note:** 1147 Fuel cell technology merges into this entry; the underlying technology is described within the vehicle context.
