Adaptability of Heteropolytungstate Anions as Efficient Anode Redox Mediators in Redox Flow Polymer Electrolyte Fuel Cells

In this study, heteropolytungstate anions with different heteroatoms were adapted as anodic redox mediators in a redox flow PEFC. In power generation tests, the redox flow PEFC with an anolyte of zinctungstate anion showed the highest performance. Zinctungstate anion exhibited the fastest reduction and oxidation rates among the W-HPAs investigated in this study.PMID:38628077 | DOI:10.1002/cssc.202301305
