Monolithic carbon aerogels for fuel cell electrodes

摘要: ABSTRACT Electrical vehicles (Zero Emission Vehicles) represent a very elegant solution in order to decrease pollution industrialised cities. To meet the requirements, it is envisaged replace gasoline engines by light fuell cells. They necessitate good electroconductive carbon monolithic electrodes. Monolithic organic resorcinol-formaldehyde aerogels (carbogels) can easily be made using sol gel method accompanied supercritical drying process liquid CO 2 (critical temperature = 31 °C). Thereafter, these copolymer carbogels are pyrolysed an atmosphere of N at 1050 °C for 3 hours, obtain carbogels. The impregnated H PtCl 6 weight % metal equal 0.44. In this work, unique solvent used was acetone each step, - reactions were catalysed perchloric acid, from synthesis up final impregnation monoliths. advantages new preparation compared aqueous former one.
