(385a) Harmonic Enhancement of Activity and Stability of Iridium-Based Catalysts for Proton Exchange Membrane Water Electrolysis
AIChE Annual Meeting
Tuesday, November 16, 2021 - 12:30pm to 12:55pm
In this presentation, new synthetic approaches for harmonic enhancement of the activity and stability will be discussed. For example, a novel solution process using ethylene glycol, formic acid, and sodium acetate for breaking the trade-off relationship of the activity and stability  is presented, which is very suitable for mass production of IrOx catalyst because it is simple and less time-consuming. As the second example, the modified Adams fusion synthesis using glycol as an additive, which can produce a higher surface area of IrOx catalyst is displayed. The harmonized activity and stability obtained by a modified Adams method results in the enhancement of the MEA performance under PEMWE conditions.
