fuel cell
C1Technical/Scientific, Business/Industry, Academic
Definition
Meaning
A device that generates electricity by a chemical reaction, typically combining hydrogen and oxygen, without combustion.
Any electrochemical cell that converts the chemical energy of a fuel and an oxidizing agent into electricity on a continuous basis. By extension, the technology and systems associated with this power generation method.
Linguistics
Semantic Notes
A compound noun where 'fuel' specifies the type of cell. It is a hyponym (specific type) of 'cell' in electrochemistry. It implies a continuous process, unlike a battery which stores energy.
Dialectal Variation
British vs American Usage
Differences
Spelling is identical. Usage is consistent, with no significant lexical or syntactic differences.
Connotations
Neutral and technical in both varieties. Associated with clean energy, innovation, and sustainability.
Frequency
Equally frequent in technical and environmental contexts in both regions.

Examples
By Part of Speech
verb
British English
- The prototype vehicle is fuelled by a hydrogen fuel cell.
- We plan to fuel-cell the entire data centre for backup power.
American English
- The prototype vehicle is fueled by a hydrogen fuel cell.
- They aim to fuel-cell the new factory to meet emissions targets.
adjective
British English
- The fuel-cell bus trial was a success in London.
- They attended a fuel-cell technology exhibition.
American English

- He works in fuel-cell research and development.
Examples
By CEFR Level
- A fuel cell makes electricity.
- Some buses use a fuel cell.
- A fuel cell produces electricity from hydrogen and oxygen.
- Cars with fuel cells are better for the environment.
- The efficiency of a hydrogen fuel cell is significantly higher than that of an internal combustion engine.
- Several companies are investing heavily in fuel cell technology for heavy transport.
- The polymer electrolyte membrane fuel cell's performance degrades if contaminated by carbon monoxide.
- Economies of scale are crucial for making fuel-cell vehicles cost-competitive with traditional alternatives.
Learning
Memory Aids
Mnemonic
Think of a 'cell' that is 'fed' by fuel (like hydrogen) to produce electricity, similar to how a living cell uses nutrients.
Conceptual Metaphor
A CHEMICAL BATTERY; A CLEAN ENGINE; AN ELECTRON PUMP.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid calquing as 'топливная ячейка' in all contexts – while technically correct, in general texts 'топливный элемент' is the standard, more natural term.
- Do not confuse with 'батарея' (battery), which implies energy storage rather than generation.
Common Mistakes
- Using 'fuel cell' and 'battery' interchangeably. A battery stores energy; a fuel cell generates it from an external fuel supply.
- Incorrect plural: 'fuels cells' instead of 'fuel cells'.
- Misunderstanding: Thinking it burns fuel.

FAQ
Frequently Asked Questions
No. While both are electrochemical cells, a battery stores chemical energy internally, whereas a fuel cell generates electricity continuously from an external fuel supply (like hydrogen).
The Proton Exchange Membrane (PEM) fuel cell, which uses hydrogen fuel, is the most common type, especially for vehicles and portable applications.
If powered by pure hydrogen, the only direct emission is water. However, if the hydrogen is produced from fossil fuels, there can be upstream greenhouse gas emissions.
Yes, in technical and business jargon, 'to fuel-cell' (often hyphenated) means to power or equip something with a fuel cell system.
