Online acquisition of polarization kinetics data from impedance spectrum is critical for fault diagnosis and health assessment of fuel cells to overcome lifetime bottleneck, but it is technically ...

This paper is a laboratory experiment aimed at fabricating the different layers that make up the Proton Exchange Membrane Fuel Cell (PEMFC), assembling it, constructing the cell, and then testing it ...

Hydrogen fuel cell vehicles have long been hailed as the future of clean mobility: cars that emit nothing but water while delivering high efficiency and power density. Yet a stubborn obstacle remains.

One of the most ambitious projects in the new frontier of electric aviation is the Flying Fuel Cell concept, a hydrogen-electric hybrid system being actively pursued by several European aerospace ...

This improvement was found to result from strong magnetic interactions arising from the atomic arrangement. Even in rigorous durability tests conducted under real hydrogen fuel cell operating ...

What if the future of aviation didn’t rely on heavy lithium-ion batteries or complex hydrogen systems, but instead on a fuel as simple and abundant as sodium? At MIT, researchers are turning this bold ...

Fuel cells are not some novel new technology. In fact, most history books credit the invention of the fuel cell to Welsh chemist and physicist William Grove, who, in the late 1830s and early 1840s, ...

Hydrogen fuel cells, which power some electric cars, pack far more energy per weight than lithium-ion batteries. The devices also show promise for decarbonizing aviation, shipping, and trucking. But ...
