High temperature PEMFC membranes

Kerres et al., among others, developed the acid-base blend membranes from sulfonated polymers and aminated or other basic polymers [98] and concluded that the protonation of the basic groups is incomplete if the base is too weak [99]. Very recently, Frutsaert et al. [70] synthesized novel polymers for the development of high temperature PEMFC membranes comprising a blend of s-PEEK and a fluorinated copolymer bearing imidazole functions as pendant groups. The extensive work on intermediate temperature fuel cell membranes are well reviewed in Chap. 4 of this book including polybenzimidazole as the basic component and sulfonated and phosphonated ionomers of either nonfluorinated or partially fluorinated backbones as the acidic component. [Pg.52]

Compared with Nafion/porous PTFE and Nalion/ electrospun nano-fiber composite membranes, there are few reports of PBl/porous PTFE and PBl/electrospun nano-fiber composite membrane for high temperature PEMFC appUcatiOTi. The PBl/porous PTFE composite membrane was shown to exhibit excellent mechanical strength and good durability, which allowed researchers to reduce the membrane thickness and thus reduce the area specific resistance and ultimately improve fuel cell performance. After the report of PBl/porous PTFE composite membrane, two... [Pg.270]

As already explained, IL exhibit numerous advantages as candidates for electrolyte in high temperature PEMFC. The introduction of IL into acid-doped PBI membranes significantly increases the ionic conductivity in the polymeric electrolyte and the mechanism of conduction seems to be the same as that of H3PO4/PBI. Protons are conducted by both hopping and vehicular mechanism, but hopping is the main mechanism of conduction. Vehicular mechanism is dependent of IL content due to the availability of free ions [64]. Ye et al. [66] found that the... [Pg.289]
