Degradation Mechanism of the PFSA Membrane and Influence of Deposited Pt in the Membrane
The degradation mechanism of the perfluorosulfonic acid (PFSA) membrane was investigated by a new accelerated test method, in which the membrane was exposed to H2O2 gas. It was clarified that the degradation of the PFSA polymer proceeds via a novel degradation mechanism. Subsequently, the influence...

| Zusammenfassung: | The degradation mechanism of the perfluorosulfonic acid (PFSA) membrane was investigated by a new accelerated test method, in which the membrane was exposed to H2O2 gas. It was clarified that the degradation of the PFSA polymer proceeds via a novel degradation mechanism. Subsequently, the influence of Pt particles, which deposited in the membrane during accelerated tests, on the degradation of the membrane was investigated. It was concluded that the Pt particles will not contribute to the degradation of the membrane. |
