1. Evaluating Cathode Catalysts in the Polymer Electrolyte Fuel Cell
Abstract : The polymer electrolyte membrane fuel cell (PEMFC) converts the chemical energy of hydrogen and oxygen (air) into usable electrical energy. At the cathode (the positive electrode), a considerable amount of platinum is generally required to catalyse the sluggish oxygen reduction reaction (ORR). READ MORE

2. Climatic conditions inside nuclear reactor containments : Evaluation of moisture condition in the concrete within reactor containments and interaction with the ambient compartments
Abstract : Safety is the top priority at a nuclear facility. The nuclear power plants are designed to prevent radioactive leakage to the surroundings, both during normal operation as well as in case of a severe accident. One of the most important structures in a nuclear power plant, with regard to safety, is thus the reactor containment wall. READ MORE

5. Limiting processes in anion-exchange membrane fuel cells
Abstract : Fuel cells allow for converting chemical energy stored in hydrogen into electrical energy, with only heat and water as by-products. In a sustainable energy society, hydrogen may play an important role due to its ability to act both as an energy carrier and as a valuable chemical in the process industry. READ MORE
