Electrochemical gas evolution reactions are essential for oxygen and fuel production in space in-situ resource utilization (ISRU), yet their performance is fundamentally limited by gravity-dependent bubble removal. Under reduced-gravity conditions,...
Electrochemical ammonia oxidation reaction, when coupled with hydrogen evolution reaction, offers an energy-saving anodic alternative to the oxygen evolution reaction. However, practical implementation is limited by sluggish multistep kinetics and...

Effective control of electrolyte wettability and gas bubble dynamics at electrode surface apart from the interfacial charge transfer kinetics regulates the performance of oxygen evolution reaction. This is facilitated by...
Cathode-Vapour-Feed electrolysers are a special type of Proton-Exchange-Membrane cells. While exhibiting various properties making them especially attractive for applications in the spaceflight industry, their performance is limited by the water...
Electrochemical carbon dioxide reduction reaction (CO2RR) provides a sustainable pathway to convert the greenhouse gas CO2 into value-added fuels and feedstocks, yet its practical deployment is largely constrained by sluggish...
