Agar as a Compound of Alkaline Solid Polymer Electrolyte
Authors: , , ,
Abstract: The paper presents results of a study on the possibility of using the method of physical cross-linking for production of hydrogel alkaline electrolytes, using poly(vinyl alcohol) (PVA), agar (AG) as a gelating medium and potassium hydroxide (KOH). The optimum composition of reaction mixture and optimum procedure for production of polymer electrolytes in the form of membranes using biodegradable oligomer agar showing gelating properties were established. Detail physicochemical characterization, including assessment of thermal stability of hydrogels, their ability to absorb water phase and the possibility of ions transportation was performed. The attempts at using agar as a gelating medium and a biodegradable component of gel alkaline electrolytes have opened new perspectives for the use of these compounds are safe and environmentally friendly components of fuel cells containing alkaline water electrolytes. In order to confirm and characterize the performance of cells containing alkaline polymer electrolytes with addition of agar as a gelating agent, model elastic nickel-hydride batteries in pouch type construction, containing polymer electrolytes of optimum parameter were made and tested in defined conditions and under certain loading.
