Hydrogen molecules dissociatively adsorb at the anode and are oxidized to protons. Electrons travel through an external load resistance. Protons diffuse through the PEM under an electrochemical ...

When it is, an electrochemical ... fuel cell pictured at left, the membrane lies sandwiched between a positively charged electrode (the cathode) and a negatively charged electrode (the anode).

The comments by Pei and Heeger on our paper published in Nature Materials 1 call for a clarification of the mechanism of the operation of light-emitting electrochemical cells (LEECs). The simplest ...

This facilitated charge transport accelerates the reactions, reduces the overpotential of the cathode ... the anode and increases the lifespan of the battery. The electrochemical test cells ...

Conventional batteries have anodes and cathodes, but a new design from the University of Chicago and the University of California San Diego lacks an anode. While this has been done before ...

Researchers developed a soluble catalyst for lithium-air batteries, reducing overpotential and preventing side reactions. The ...
