Can you provide an overview of how hydrogen fuel cells work? Hydrogen polymer electrolyte membrane (PEM) fuel cells use hydrogen and oxygen to produce electricity through an electrochemical reaction.

PEM fuel cells have good efficiency and low operating temperature and could play an important role in power generation in the future. They are currently the leading technology for automotive ...

Join the audience for a live webinar at 3 p.m. GMT/10 a.m. EST on 18 February 2026 Discover the realities and requirements of ...

One of the key challenges in optimal operation of PEM hydrogen cells is to ensure optimal distribution of the liquid water inside them. Excessive accumulation of water can clog proton and electron ...

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, ...

Q: During a recent blackout, my neighbor and I kicked around the idea of alternative power sources. Besides solar and wind, he mentioned fuel cells, which I hadn’t heard much about. What is a fuel ...

Ever caught yourself daydreaming about a giant bulk carrier powered by something shinier than heavy fuel oil? Welcome to the ...

The Nyquist plot of the impedance spectra for different hydrogen partial pressures shows increasing performance losses associated with both anode and cathode processes. In a new study, researchers ...

Just when you thought you’d got a handle on the chemistry behind hydrogen fuel cells, researchers at the Fritz Haber Institute of the Max Planck Society go an ...
