Study of the use of dehydrated salts : as electrolytes in the fuel cells

Abstract

The main advantage of the non-conventional energy sources over the conventional energy sources is its cleanness, low chemical and noise pollution, high fuel efficiency with better fuel flexibility and economy. Fuel cells are electrochemical devices that convert the chemical energy of a fuel directly and very efficiently into electricity. Here we report a new class of electrolyte, i.e. polycrystalline dehydrated salts as an intermediate temperature fuel cell electrolyte. The porous conduction in the dehydrated salts was established by the study of DTA/TGA, transference number, bulk electrical conductivity measurement and EMF study.
