Brianna and Robby publish a paper highlighting impact of bulk reactor properties on local reaction environment conditions and performance outcomes

Brianna’s and Robby’s co-first-author paper establishes key design parameters for a membrane electrode assembly solid electrolyte electrolyzer and their respective impacts on electrocatalytic performance for the two-electron oxygen reduction reaction to produce hydrogen peroxide at high operating currents. This reactor design utilizes two membranes sandwiching a solid electrolyte compartment that enables production of high concentration hydrogen peroxide, without added salts or other electrolyte components, thereby significantly simplifying downstream application. This study provides insights into how macroscale system properties of this reactor design impact the local reaction environment of the complex, porous electrode structures and provides into the optimization of these reactors not only for hydrogen peroxide electrosynthesis, but for a broad range of electrochemical processes. Congratulations Brianna and Robby!
