An in situ accelerated mechanical stress test (ΔP-AMST) that applies relative humidity (RH) cycling combined with a pressure differential (ΔP) at a high temperature is proposed to accelerate mechanical degradation in all types of reinforced membran

Membrane mechanical durability is one of the primary factors limiting the lifetime of ionomer membranes in polymer electrolyte fuel cells. Due to the importance of membrane dimensional stability during relative humidity (RH) cycles on the magnitude o

For evaluating the durability of membranes in polymer electrolyte fuel cells (PEFCs) within relatively short time, accelerated stress tests (AST) are used for applying chemical and mechanical stressors by means of current density, cell voltage, tempe

The first two complexes of the trioxodinitrate anion were prepared by reaction of Zn(bipy)Cl(2).1.5H(2)O (1.1.5H(2)O) with Na(2)N(2)O(3).H(2)O in water to produce Zn(II)(bipy)(H(2)O)(N(2)O(3)) (2) and an analogous reaction of Co(bipy)(2)Cl(2).2.5H(2)
