Technical FAQs 4

What is a hydrogen fuel cell?

A hydrogen fuel cell is an electrochemical device that converts the chemical energy of hydrogen and oxygen into electricity, with water and heat as the only by-products . It is a clean energy technology that does not require combustion to operate and is very efficient.

Are hydrogen fuel cells a viable alternative to conventional combustion?

With the shift towards cleaner and more sustainable energy sources, hydrogen fuel cells are gaining attention as a powerful alternative to conventional combustion systems. These fuel cells produce zero-emission electricity and offer promising solutions for transport, industrial energy and emergency power systems.

What type of hydrogen can be stored in a fuel cell?

Compressed hydrogen is the most common way for fuel cell hydrogen storage. Hydrogen compressed up to 70 MPa is now available for fuel cell applications. Metal hydrides, which can be charged and discharged reversibly, are metallic alloys (see Hydrogen–Metal Systems: Basic Properties (1); and Hydrogen–Metal Systems: Basic Properties (2)).

What is the efficiency of a fuel cell system?

The efficiency of a fuel cell system refers to the ratio of the energy lost during the conversion process from fuel (typically hydrogen) to electrical energy, relative to the input energy.
