          Abstract

          Ionomeric binders in catalyst layers, abbreviated as ionomers, play an essential role in the performance of polymer–electrolyte membrane fuel cells and electrolyzers. Due to environmental issues associated with perfluoroalkyl substances, alternative hydrocarbon ionomers have drawn substantial attention over the past few years. This review surveys literature to discuss ionomer requirements for the electrodes of fuel cells and electrolyzers, highlighting design principles of hydrocarbon ionomers to guide the development of advanced hydrocarbon ionomers.

          Abstract

          Ionomers in the catalyst layers are a critical component for fuel cells and electrolyzers. This review provides the current understanding of the performance‐limiting factor of ionomers from literature over the past three decades. The remaining challenges and design aspects of fluorine‐free hydrocarbon‐based ionomers are discussed to develop more advanced fuel cells and electrolyzers.
