For heavy-duty vehicles like long-haul trucks, batteries often fall short. They take too long to charge and weigh too much.

Hydrogen fuel cells are a promising candidate to replace internal combustion engines, especially for heavy-duty vehicles like ...

Fuel cells simply separate different parts of a chemical reaction so that the electrons that are transferred during the reaction can be used as a source of electricity.

With a fuel cell, as long as there is a flow of the chemical elements hydrogen and oxygen into the cell, electricity will flow out of the cell. Fuel cells designed to run on hydrogen combine ...

Fuel cells use a simple chemical reaction, such as the combination of oxygen and hydrogen to form water, to generate electricity. The question of which is the best material to use when making ...

The cells of all living organisms are powered by the same chemical fuel: adenosine triphosphate (ATP). Now, researchers have found a way to generate ATP directly from electricity, which could ...

A new sodium-air fuel cell could be a more practical and sustainable power source (Joule 2025, DOI: 10.1016/j.joule.2025.101962). The fuel cell has an energy density of over 1,000 W h/kg, roughly ...

In research that could jumpstart work on a range of technologies including fuel cells – key to storing solar and wind energy – MIT researchers have found a relatively simple way to increase ...

University of Delaware College of Engineering postdoctoral researcher Teng Wang, Professor Yushan Yan and their Switzerland-based collaborators have published findings in Nature Materials on a new ...

Very early fuel cells — starting with Gemini in 1962 — used a proton exchange membrane. However, in 1967, NASA started using Nafion from DuPont ...
