Download or read book PEM Fuel Cells written by Yun Wang and published by Momentum Press. This book was released on 2013-04-06 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymer Electrolyte Membrane (PEM) fuel cells convert chemical energy in hydrogen into electrical energy with water as the only by-product. Thus, PEM fuel cells hold great promise to reduce both pollutant emissions and dependency on fossil fuels, especially for transportation—passenger cars, utility vehicles, and buses—and small-scale stationary and portable power generators. But one of the greatest challenges to realizing the high efficiency and zero emissions potential of PEM fuel cells technology is heat and water management. This book provides an introduction to the essential concepts for effective thermal and water management in PEM fuel cells and an assessment on the current status of fundamental research in this field. The book offers you: • An overview of current energy and environmental challenges and their imperatives for the development of renewable energy resources, including discussion of the role of PEM fuel cells in addressing these issues; • Reviews of basic principles pertaining to PEM fuel cells, including thermodynamics, electrochemical reaction kinetics, flow, heat and mass transfer; and • Descriptions and discussions of water transport and management within a PEM fuel cell, including vapor- and liquid-phase water removal from the electrodes, the effects of two-phase flow, and solid water or ice dynamics and removal, particularly the specialized case of starting a PEM fuel cell at sub-freezing temperatures (cold start) and the various processes related to ice formation.

Available in PDF, EPUB and Kindle. Book excerpt: Pediatric patients are a unique subset of emergency patients, making up about one-quarter of all emergency department visits. Textbooks regarding the care of pediatric patients are almost universally organized by organ system, which does not facilitate an efficient diagnosis. Taking a case-based approach, Pediatric Emergency Medicine: Chief Complaints and Differential Diagnosis is arranged by chief complaint, using real patient scenarios to help the reader work through the inductive and deductive reasoning needed to assess, evaluate, treat, and disposition pediatric patients with urgent complaints. Cases are structured in the way in which they are presented during medical care, allowing practitioners to become comfortable with the general structure of case presentations: chief complaint, HPI, PMH, ROS, exam, and ancillary studies. This volume also discusses disease processes and their differentiations, providing in-depth knowledge regarding current standards of diagnosis and care.

This book was released on 2015-11-11 with total page 1552 pages. Available in PDF, EPUB and Kindle. Book excerpt: Before the 1st edition of the Textbook of Pediatric Emergency Medicine published, there was no official pediatric emergency medicine subspecialty in either pediatrics or emergency medicine. This book defined many of the treatments, testing modalities procedural techniques and approaches to care for the ill and injured child. As such, it was written with both the pediatrician and the emergency physician in mind. The Textbook of Pediatric Emergency Medicine, has an entirely new editorial board and templated chapters focusing on evidence-based diagnosis and management of pediatric patients in the ED. The book’s content has been rewritten to eliminate and eliminate redundancy, creating succinct sections that pertain to patient care in the ED. Templated chapters include: Clinical Outcomes/Goals of Therapy Current Evidence Clinical Considerations Clinical Recognition: Triage Initial Assessment Management/Diagnostic Testing Clinical indications for discharge or admission, including parental instructions References In the ED, nurses and physicians work closely as a paired team, thus this edition reflects that partnership and offers content tailored to it. Online ancillaries, found in the bundled eBook, include Learning Links for nursing considerations and clinical pathways that outline the key steps to take when managing critically ill patients.
