ISBN-13: 9781441944627, 978-1441944627 Synopsis From the late-1960's, perfluorosulfonic acid (PFSAs) ionomers have dominated the PEM fuel cell industry as the membrane material of choice. The "gold standard' amongst the many variations that exist today has been, and to a great extent still is, DuPont's Nafion (R) family of materials. However, there is significant concern in the industry that these materials will not meet the cost, performance, and durability requirementsnecessary to drive commercialization in key market segments - es- cially automotive. Indeed, Honda has already put fuel cell vehicles in the hands of real end users that have home-grown fuel cell stack technology incorporating hydrocarbon-based ionomers. "Polymer Membranes in Fuel Cells" takes an in-depth look at the new chem- tries and membrane technologies that have been developed over the years to address the concerns associated with the materials currently in use. Unlike the PFSAs, which were originally developed for the chlor-alkali industry, the more recent hydrocarbon and composite materials have been developed to meet the specific requirements of PEM Fuel Cells. Having said this, most of the work has been based on derivatives of known polymers, such as poly(ether-ether ketones), to ensure that the critical requirement of low cost is met. More aggressive operational requi- ments have also spurred the development on new materials; for example, the need for operation at higher temperature under low relative humidity has spawned the creation of a plethora of new polymers with potential application in PEM Fuel Cells.

When it looked like the book wasn't going to arrive, i rang 'Books etc.' Told to wait another day or so. Book still didn't arrive. Rang back and was given an apology and a full refund. Each time the staff were decent and friendly on the phone. However, this is the 2nd time of "no book showing up" from them (I'd previously ordered 'Daily Doctrine' from them, via Amazon, on 28th Jan- again, was given a full refund by them. Their prices are v good but will I ever buy ftom them again? Unlikely.

Fantastic experience with this seller. I had an issue with the clay in my kit being dried out, which is something they couldn't have known about before me opening the box. I sent them a message and they replied quickly and kindly with a resolution, replacing my kit for me. Overall the kit was fantastic value and arrived brand new, in perfect condition bar the clay. Very trustworthy and helpful.
