    Sammanfattning : Ionic liquids (ILs) have gained popularity as “green” and safe replacements for conventional organic solvents. They are defined as ionic salts displaying a melting point below 100 °C. Some of their unique characteristics also include negligible vapour pressure, good electrical conductivity as well as good thermal and chemical stability. LÄS MER

  4. 3. Structure, interactions and functionality in novel electrolyte materials for fuel cell applications

    Författare :Anna Martinelli; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; proton conductivity; ionic liquids; Polymer electrolyte membrane PEM ; fuel cell; vibrational spectroscopy;

    Sammanfattning : It is today well known that fossil fuels will sooner or later be depleted, and the need to find alternative energy sources is now accepted. Among the diverse technologies developed to produce energy, considerable interest is currently directed to the hydrogen fuel cell, a device that converts chemical into electrical energy, is versatile and has a low environmental impact.
