I am a student of chemical engineering.. i need to prepare a ppt on High temperature polymers.. need some help or advised ppt for reference as soon as possible.
Or if possible, i want to work on the recent advancements in the development of processable high temperature polymers because i need to make the ppt in specific topic rather than on a generalize field.
i would also like to work on the ppt of the following topic whose abstract is as follows- PEMFC systems: the need for high temperature polymers as a consequence of PEMFC water and heat management
Abstract
The proton exchange membrane fuel cell (PEMFC) is usually operated at elevated pressure, requiring the use of a compressor. Also the operating temperature is low, generally below 80 °C. For many applications, a somewhat higher operating temperature would be preferable. This paper describes the reasons for pressurised operation at, or close to, 80 °C in terms of water and heat management issues. It is concluded that a new type of proton conducting material is highly desirable, having many of the good Nafion properties, but based on a proton conduction mechanism that does not require the presence of large amounts of water in the electrolyte.
thank you.. waiting for the help.
