Advanced Materials in Polymer Electrolyte Fuel Cells
Polymer electrolyte fuel cells (PEFCs) have attracted much interest due to the need for an efficient, non-polluting power source with high energy density for vehicles in urban environments, as well as portable electronics [...].
متن کاملCharacterizing Electrode-Level Oxygen Transport in Polymer Electrolyte Fuel Cells
Polymer electrolyte fuel cells (PEFCs) are a promising technology for environmentally friendly automobiles, among other applications. However, performance losses due to oxygen transport hindrances in the PEFC’s cathode continue to be an issue in widespread commercialization. This dissertation focuses on the transport of oxygen through the thickness of the PEFC cathode, and the effect of the cat...
متن کاملCatalyst supports for polymer electrolyte fuel cells.
A major challenge in obtaining long-term durability in fuel cells is to discover catalyst supports that do not corrode, or corrode much more slowly than the current carbon blacks used in today's polymer electrolyte membrane fuel cells. Such materials must be sufficiently stable at low pH (acidic conditions) and high potential, in contact with the polymer membrane and under exposure to hydrogen ...
متن کاملFabrication of bifunctional membrane electrode assemblies for unitised regenerative polymer electrolyte fuel cells
Introduction: The conversion and storage of energy with a high efficiency, especially a high specific energy, will be an important factor in future energy storage technologies. The relatively simple possibility to store hydrogen and oxygen with high specific energy combined with high energy conversion efficiency in fuel cells and electrolyser presents an opportunity for the use of polymer elect...
متن کاملSynthesized Bimetallic Electrocatalyst for Oxygen Reduction Reaction in Polymer Electrolyte Fuel Cells
In the present study, a step by step process was applied to synthesize bimetallic electrocatalyst (Ru and Pt on VulcanXC-72R). This process can reduce the amount of platinum and increase the gas diffusion electrode (GDE) performance in the cathodic reaction of polymer electrolyte membrane fuel cells (PEMFCs). Using the impregnation by hydrothermal synthesis method, a series of electrocatalysts ...
