Operando X-ray Fluorescence Analysis of Through-plane Cerium Ion Radical Quencher Migration in Polymer Electrolyte Fuel Cells

Polymer electrolyte fuel cells (PEFCs) need to achieve long-term durability for widespread commercialization. Chemical degradation of the perfluorosulfonic acid (PFSA) membrane caused by radical species (·OH) can be mitigated by adding cerium ions as radical scavengers; however, cerium ions migrate...
