Description
Perfluorinated Polymer Electrolyte Membranes for Fuel Cells, Paperback by Okada, Tatsuhiro (EDT); Saito, Morihiro (EDT), ISBN 1604568046, ISBN-13 9781604568042, Brand New, Free shipping in the US In this book the authors focus on the ion and water transport characteristics in Nafion and other perfluorinated ionomer membranes that are recently attracting attention in various fields such as water electrolysis, mineral recovery, electrochemical devises and energy conversion. Methodology of measurements and data analysis is presented that enables basic characterization of transport parameters in the perfluorinated ionomer membranes. An analytical formulation of membrane transport equations with proper boundary conditions is proposed, and using various parameters of membrane transport, a simple diagnosis of water dehydration problem is carried out. This analysis leads one to an effective control of fuel cell operation conditions, especially from viewpoint of proper water management.

The book I bought was reasonably priced and when it arrived it was in the 'Like New' condition specified in the listing. However, when I saw that the seller had not shipped the book after more than 15 days had passed since my order I felt I must write to say that I had actually placed an order with the seller and inquire when it planned to send the book. The brusque reply was that a tracking number was available, but no number HAD been created until I pointed out that I had placed the order.

Item as described. Poly mailer, no padding. Description clearly states delivery window of several weeks. Yet I chose this seller because item is new. Purchased/paid April 16, shipped April 28, arrived Maryland to SC May 5.This after contacting seller on day 10 to ask why it had not shipped yet. Slow return communication requesting invoice number/transaction date. Just be aware. IMHO eBay has sellers with faster, more efficient delivery service.
