Polymer Membranes for Fuel Cells by Javaid Zaidi,Takeshi Matsuura

By Javaid Zaidi,Takeshi Matsuura

From the late-1960’s, perfluorosulfonic acid (PFSAs) ionomers have ruled the PEM gasoline phone because the membrane fabric of selection. The “gold ordinary’ among the various diversifications that exist at the present time has been, and to an excellent volume nonetheless is, DuPont’s Nafion® relatives of fabrics. despite the fact that, there's major trouble within the that those fabrics won't meet the fee, functionality, and sturdiness requirementsnecessary to force commercialization in key industry segments – es- cially car. certainly, Honda has already positioned gas cellphone cars within the palms of genuine finish clients that experience home-grown gasoline mobile stack know-how incorporating hydrocarbon-based ionomers. “Polymer Membranes in gas Cells” takes an in-depth examine the recent chem- attempts and membrane applied sciences which have been constructed through the years to handle the worries linked to the fabrics at the moment in use. in contrast to the PFSAs, which have been initially built for the chlor-alkali undefined, the newer hydrocarbon and composite fabrics were built to fulfill the explicit standards of PEM gasoline Cells. Having acknowledged this, many of the paintings has been in line with derivatives of recognized polymers, akin to poly(ether-ether ketones), to make sure that the severe requirement of not pricey is met. extra competitive operational requi- ments have additionally spurred the advance on new fabrics; for instance, the necessity for operation at greater temperature below low relative humidity has spawned the construction of a plethora of recent polymers with capability software in PEM gasoline Cells.

Polyhydroxyalkanoates from Palm Oil: Biodegradable Plastics (SpringerBriefs in Microbiology)

The environmental difficulties brought on by petroleum-based plastic and plastic waste have ended in an expanding call for for biobased and biodegradable plastics, corresponding to polyhydroxyalkanoates (PHAs). those polyesters are synthesized from carbon resources, e. g. sugar and plant oils, by means of a variety of micro organism. This publication highlights the possibility of plant oils, in particular palm oil, as a feedstock for PHA creation.
