In situ infra-red spectroscopy of electrode ionomer networks for electrochemical energy system applications

While hydrogen technologies such as fuel cells and water electrolyzers are expected to play pivotal roles in the upcoming energy transition, their insufficient durability continues to hinder their wider adoption. Longevous fuel cells and electrolyzers demand durable materials (i.e., solid electrolytes) that can withstand the corrosive environment within these devices. However, the mechanisms of solid electrolyte degradation and their effect on device performance remain poorly understood. Understanding those mechanisms is an important first step to designing durable solid electrolytes for next generation fuel cells and electrolyzers. The proposed research project is to revolutionize our fundamental understanding of, and develop predictive modelling tools for, solid electrolyte degradation in fuel cells and electrolyzers. We will couple our accelerated electrolyte degradation and characterization techniques with the unique in situy infrared spectroscopy capabilities pioneered by Dr. Chevalier’s group, to generate a first-of-its-kind dataset that can inform novel solid electrolyte designs and operating strategies for durable fuel cells and electrolyzers.
