Abstract:

Proton exchange membrane water electrolysis (PEMWE), recognized as an efficient and eco-friendly hydrogen production technology, has garnered significant attention for its potential to expedite the transition toward a sustainable energy framework. Nonetheless, the widespread adoption of PEMWE is hindered by factors such as cost and longevity. Addressing these challenges necessitates foundational research, particularly in the realm of insitu electrochemical characterization. Cyclic voltammetry (CV) testing emerges as a pivotal technique in this context, offering insights into critical electrochemical parameters including the electrochemical active surface area (ECSA) and catalyst efficiency, among others. The requirement for humidified gas during CV testing presents a notable obstacle for PEMWE applications. This study systematically investigates the conditions requisite for effective PEMWE CV testing, aiming to establish a more feasible methodology for conducting these assessments.
