Fuel Cells (GCSE Chemistry)

Which property of fuel cells makes them attractive for backup power in data centres?

One advantage of a hydrogen fuel cell over a combustion engine is:

What is one disadvantage of producing hydrogen by steam reforming of natural gas compared with producing hydrogen by water electrolysis using renewable electricity?

What is a common safety concern with storing hydrogen on vehicles?

In a PEM fuel cell, what does the membrane primarily allow to pass through it?

Which of the following is the overall chemical reaction in a typical hydrogen fuel cell?

How can carbon monoxide (CO) in hydrogen fuel be reduced to avoid poisoning fuel cell catalysts?

Which fuel cell type is most commonly used in vehicles and small-scale applications due to its low operating temperature and fast start-up?

How does raising the temperature generally affect the performance of a solid oxide fuel cell (SOFC)?

What role does the catalyst play at the fuel cell electrodes?

At the anode of a proton exchange membrane (PEM) fuel cell, which half-reaction occurs?
