Perovskite‐Based Catalysts for the Oxygen Evolution Reaction: Synthesis, Device Relevant Performance, and Scale‐Up Strategies

Small, EarlyView.
Perovskites are emerging as catalysts for acidic oxygen evolution in proton exchange membrane water electrolyzers. This manuscript focuses on catalyst behavior under device‐relevant conditions, highlighting surface reconstruction, elemental utilization, and membrane electrode assembly performance. By linking materials design with electrolyzer operation,

Observations of hollow cathode light emission from a transient hollow cathode discharge

Applied Physics Letters, 1991
Experimental observations are presented on the light emission from the hollow cathode region of a pulsed hollow cathode discharge. A 2 mJ, 30 ns, 1.06 μm laser pulse incident on the back of the cathode is used to trigger the discharge. The temporal evolution of the light emission from this region is recorded in 50 nm spectral bands.

Physical Processes in Hollow Cathodes

AIAA Journal, 1976
Hollow cathodes with cavity diameters of 1.9 cm have been operated in an MPD arc configuration at discharge currents from 0.25 kA to 30 kA. Current and potential distributions, measured with probes in the cathode cavity, show that a spontaneous mode of hollow cathode operation, wherein the current distribution penetrates upstream into the cavity, has ...

Hollow Cathode Discharge with Thermionic Cathodes

Journal of Applied Physics, 1971
The electrical and visual characteristics of a dc hollow cathode discharge with indirectly heated thermionic cathodes were obtained in argon at a few Torr. Two facing planar cathodes of variable separation form the hollow cathode geometry. A hollow cathode effect was observed in the ``ball-of-fire'' mode and in the ``low-voltage arc'' mode. The results
