Abstract:Understanding the H3PO4 effect
on the catalyst’s
activity under a relevant condition is important for high-temperature
polymer electrolyte membrane fuel cell (HT-PEMFC) catalyst research.
Here, we report a high-temperature rotating disk electrode (HT-RDE)
study of oxygen reduction reaction (ORR) in H3PO4. With the regular electrochemical protocol, we found that H3PO4 reduction could occur during cyclic voltammetry
study and form a reductive speciesphosphorus acid (H3PO3). To obtain reliable ORR measurement, w… Show more
“…15d and e). 80 Under conventional electrochemical schemes, it was observed that the reducing substance PA (H 3 PO 3 ) undergoes oxidation by H 3 PO 4 reduction during cyclic voltammetry (CV) cycles. In order to obtain reliable ORR measurements, the testing plan was optimized to avoid the formation of H 3 PO 3 .…”

The current challenges and opportunities faced by HT-PEMFCs are discussed, as well as possible future solutions. This review can provide guidance for the future development of high-performance HT-PEMFC catalysts.
