Experimental observations are presented of prebreakdown electron beam generation in a transient hollow cathode discharge (THCD) in a vacuum. The discharge driver consists of a 400-kV maximum voltage, 25-nF Marx operated ...

The amount and distribution over the active area of current density produced by the stack is a key aspect of a fuel cell performance. The performance of a proton exchange membrane fuel cell (PEMFC) is affected by many ...

The cathode-sheath region of a discharge in atmospheric pressure air with a flat copper cathode is numerically investigated by using a simple fluid model that takes into account non-local ionization. The effects of the ...

Chlor-alkali electrolysis continues to pose challenges for researchers. Replacement of the hydrogen-evolution reaction by the oxygen-reduction reaction can reduce the overpotential of the cathodic process, depolarizing the ...

This work presents the results from the development of bio-cathodes for the application on paper-based biofuel cells. Our main goal here is to demonstrate the possibility of using different designs of air-breathing ...

In this report we track the structural changes suffered by ITO along galvanostatic polarization at different current densities by X-ray diffraction and SEM micrographs. The XRD shown that cathodic treatment induces structural ...

The influence of current density, at the interval 5-100 mA cm-2, on the structural and magnetic properties of electrodeposited (Co 100-xNix)100-yWy alloys (x = 23-33.5 at. % Ni, y = 1.7-7.3 at. % W) was studied from a ...
