Latest Patents

Wei-Qiao Deng holds 1 patent for his invention titled "Carbon based electrocatalysts for fuel cells." This patent describes novel proton exchange membrane fuel cells and direct methanol fuel cells that utilize nanostructured components. These advancements lead to a higher precious metal utilization rate at the electrodes, increased power density, and reduced costs. The catalyst is formed by depositing platinum or platinum-ruthenium nanoparticles onto various carbon-based materials, including single-walled, dual-walled, multi-walled, and cup-stacked carbon nanotubes. The deposition process employs an ethylene glycol reduction method, and aligned arrays of these carbon nanomaterials are prepared by filtering them with ethanol. A membrane electrode assembly is created by sandwiching the catalyst between a proton exchange membrane and a diffusion layer, forming the first electrode. The second electrode can be constructed using a conventional catalyst. The several layers of the membrane electrode assembly are hot pressed to create an integrated unit, allowing for the development of proton exchange membrane fuel cells and direct methanol fuel cells by stacking the assemblies in a conventional manner.
