In this course, three types of energy production and storage technologies will be analyzed. The first type is the batteries, whose principle of operation is based on the spontaneous conversion of the chemical energy of the reactants inside the battery into electricity. The second type is the fuel cells, where spontaneous conversion of chemical energy into electricity again occurs, but the chemical reactants are continuously provided into the electrochemical device. The third type concerns the production, storage and management of hydrogen, which is a zero-emission fuel and could be used in both electrochemical power plants and internal combustion engines.
