The hydrogen economy is rapidly moving from concept to future reality. This outlook is based on the carbon-free production and storage of H2, primarily through electrocatalysis coupled with renewable energy sources. In electrocatalysis, the reaction occurs at the electrode-electrolyte interface. Here, electric double layer (EDL) theory formulates unique interfacial arrangements of electrolyte components, allowing researchers to hypothesize that modifying the EDL structure could improve electrocatalytic performance, while remaining largely unexplored. We have investigated to answer the question of how the EDL structure affects electrocatalysis. I will present several case studies that show the impact of the EDL structure on the kinetics and mass transport of electrocatalysis. Finally, our efforts to translate the fundamentals into practical applications will also be discussed, emphasizing the critical role of polymer science in realizing the H2 economy as a tangible future.
