Identifiability analysis of degradation model parameters from transient CO2 release in low-temperature PEM fuel cell under various AST protocols
Andraž Kravos, Ambrož Kregar, Kurt Mayer, Viktor Hacker, Tomaž Katrašnik
Izvirni znanstveni članek
Oznake: platinum degradation;mechanistic modeling;transient real-time modeling;accelerated stress tests;
The detrimental effects of the catalyst degradation on the overall envisaged lifetime of low-temperature proton-exchange membrane fuel cells (LT-PEMFCs) represent a significant challenge towards further lowering platinum loadings and simultaneously achieving a long cycle life. The elaborated physica ...

Polysaccharide anion exchange membranes (AEMs) containing chitosan (CS), cellulose nanofibrils (CNFs) and CNFs quaternized with poly(diallyldimethylammonium chloride) (CNF(P)s) were developed for use in alkaline direct ethanol fuel cells (ADEFCs). The resulting composite membranes prepared by the so ...
