GNPS Seven Intel Semifinalists

Debbie Yee's project was "Using Thiol-functionalized Metallic Nanoparticles to Increase the Efficiency of the Polymer Electrolyte Membrane (PEM) Fuel Cell." She wrote that the Polymer Electrolyte Membrane Fuel (PEM) fuel cell shows great promise as an alternative energy source to fossil fuels since it has a high efficiency and is environmentally friendly, producing water as its only byproduct. Her project used Gold and palladim nanoparticle catalysts to increase the power output of a single PEM fuel cell. She synthesized the nanoparticles and deposited them onto Nafion, the electrolyte membrane in the fuel cell. The Gold and palladium yielded a 30 and 10 percent increase in power output over the control, respectively.
