Several roadblocks prevent the large-scale commercialization of hydrogen fuel cells, including the stability of the Pt catalysts and their substrates, as well as the high cost of Pt. This is particularly true for the cathode, which requires a higher Pt loading because of the slow kinetics of the oxygen reduction reaction (ORR). The problem with the stability of the substrate can be solved by replacing the traditional carbon support with a conductive metal oxide such as reduced TiO2, which will not easily corrode and should result in longer lasting fuel cells. In this study, Pt was deposited either by atomic …

In order to reduce the emissions of greenhouse gases and reduce dependence on the use of fossil fuels, it is necessary to pursue alternative sources of energy. Transportation is a major contributor to the emission of greenhouse gases due to the use of fossil fuels in the internal combustion engine. To reduce emission of these pollutants into the atmosphere, research is needed to produce alternative solutions for vehicle transportation. Low temperature polymer electrolyte membrane fuel cells are energy conversion devices that provide an alternative to the internal combustion engine, however, they still have obstacles to overcome to achieve large scale …
