Magnetically induced convection enhances water electrolysis in microgravity

This study demonstrates that magnets can significantly improve water electrolysis efficiency in microgravity, by enhancing gas bubble detachment and movement through magnetohydrodynamic and magnetic polarization forces. Two proof-of-concept devices were developed: a proton-exchange membrane electrolyser and a magnetohydrodynamic drive, both demonstrating near-terrestrial performance in microgravity without moving parts.

The diamagnetic and MHD electrolysis technologies described are covered by US patent 2023/0265573 A1 and US patent application 63/399784 issued by the University of Colorado Boulder and the Georgia Institute of Technology on behalf of Álvaro Romero-Calvo.

This study presents a novel approach to enhance water electrolysis in microgravity using magnetically induced convection, with practical implications for space exploration. The experimental results support the proposed method and are complemented by theoretical framework and simulations. The disclosed conflict of interest is noted but does not significantly detract from the research value.
