Environmental problems such as global warming, pollution in our cities and the depletion of fossil fuel resources have conspired to make both the development of renewable energy and the shift to electrical transportation crucial. Proton exchange membrane fuel cells, which efficiently convert chemical energy into electrical energy via oxidation and reduction reactions, are receiving considerable attention as an alternative energy source because of their high energy efficiency and no emissions of pollutants. Electrical transportation applications require the storage of a large amount of energy on board vehicles so as to enable long cruising distances. Recently, we have prepared all solid polymer electrolyte membranes composed of ion conductive nanofibers and revealed that the composite membranes showed a higher ion conductivity (i.e. proton or lithium ions) than the membrane without nanofibers. In this paper, we reported the properties of novel all solid electrolyte membranes comprising an ion conductive nanofiber framework as fuel cells and lithium ion batteries.
