Various types of fuel cells exist, but the one automakers are ... While hydrogen is fed to the anode, oxygen is fed to the cathode, where a catalyst creates oxygen ions. The arriving hydrogen ...

Lin Zhuang of Wuhan University in China has developed a different fuel cell using a nickel catalyst on the anode. This catalyst triggers the generation of hydroxyl (OH) ions which are alkaline.

By keeping the electrode potential as close as possible to the thermodynamic potential for OER, other components in the fuel cell, such as platinum ... of both is higher in comparison with similar OER ...

Abstract: In order to improve the electricity generation performance of fuel cell electric vehicles, it is necessary to optimize the microstructure of the catalyst layer of a polymer electrolyte fuel ...

You can think of it as an electrolyte. Common fuel cells use an electrode design that hasn’t changed in decades. The new research has catalyst ridges separated by empty grooves. This enhances ...

However, fuel cell catalysts, which are crucial materials for promoting electricity generation reactions, generally undergo structural damage or catalyst loss during operation, leading to a gradual ...

The dispersing solvent used for fuel cell catalyst ink preparation plays a vital role in establishing the resulting morphology of the electrode layers, which in turn will impact the performance of ...

A fuel cell is a device that generates electric energy through electrochemical reactions between an oxidizing agent and a fuel – a material that stores energy in chemical form. Both species are ...

However, the core material of the fuel cell catalyst, which promotes the electricity generation reaction, cannot avoid structural damage or gradual performance degradation during use. This ...
