Fuel Cells

A fuel cell is an electrochemical device that converts the chemical energy of a fuel directly into electricity, with high efficiency and low emissions.

Unlike batteries, fuel cells run continuously as long as fuel is supplied.

Electrochemistry and Types

In a fuel cell, fuel is oxidized at the anode and oxygen reduced at the cathode, with ions moving through an electrolyte to generate current. Types are classified by their electrolyte: PEM, alkaline, phosphoric acid, molten carbonate and solid oxide fuel cells.

Each type suits different temperatures and applications, from portable power to large stationary plants.
