Fuel Cell Mechanism
Captions available
The idea
A fuel cell generates current from a redox reaction between continuously supplied reactants, functioning as long as fuel and oxidant are resupplied, unlike a battery's fixed supply.
In practice
A hydrogen fuel cell consumes hydrogen and oxygen fed in continuously, producing water and current.
Where people slip
A fuel cell is not a battery with unlimited charge — it needs continuous external reactant supply.
