Abstrak

This study investigates water transport in a polymer electrolyte membrane (PEM) electrolyzer using operando infrared spectroscopic imaging. By testing different H2SO4 anolyte concentrations, it examines electrochemical performance, water diffusion, and membrane hydration. Higher anolyte concentrations increased standard deviations in current densities and led to water diffusion gradients revealed by infrared imaging and confirming localized water transport variations. The study highlights the need for improved water management and optimized electrolyzer design for stable and efficient PEM electrolysis in industrial applications.
