Cathode and Anode: These terms are widely used in electrolysis and electrochemical systems. Understanding them is important, as their charges vary based on the system and reaction they are involved in ...

A recent forum post reminded me of a common issue we see here at Screaming Circuits – ambiguous diode polarity marking. To start with, some diode manufactures mess with our heads where polarity ...

A diode is a device that allows electric current to flow in only one direction, from its anode towards its cathode but not the other way around. There is plenty of online material explaining diode ...

In HT-PEMFCs, hydrogen is oxidized at the anode to generate protons, which are transported to the cathode through the proton conductor phosphoric acid in the high-temperature proton exchange membrane.

I n an idealized diode, no reverse current flows from cathode to anode when the device is reverse-biased. However, with real-world diodes, large amounts of stored charge can flow from the cathode—back ...

A new approach to elucidate the operation and control of Polymer Electrolyte Membrane (PEM) fuel cells is being developed. A global reactor engineering approach is applied to PEM fuel cells to ...
