Technical FAQs 4

What are fuel cells used for?

Fuel cells can be used in a wide range of applications, providing power for applications across multiple sectors, including transportation, industrial/commercial/residential buildings, and long-term energy storage for the grid in reversible systems.

Are fuel cells eco-friendly?

Fuel cells have attracted attention as they are eco-friendly energy generators that convert chemical energy to electrical energy electrochemically . Like batteries, fuel cells use electrodes and electrolytes but produce continuous electricity via an external fuel supply rather than storing energy .

What is a hydrogen fuel cell?

If hydrogen is the fuel, the only products are electricity, water, and heat. Fuel cells are unique in terms of the variety of their potential applications; they can use a wide range of fuels and feedstocks and can provide power for systems as large as a utility power station and as small as a laptop computer.

Are fuel cells economically viable?

While combined heat and power (CHP) units such as fuel cells operating solely for electricity generation are not economically viable, the cogeneration mode offers efficient power. As such, the technical, economic, and environmental aspects of fuel cell deployment in energy systems must be evaluated.
