New Findings from J.B. Liu and Colleagues Has Provided New Data on Fullerenes

March 7, 2014



By a News Reporter-Staff News Editor at Energy Weekly News -- Current study results on Fullerenes have been published. According to news originating from Austin, Texas, by VerticalNews correspondents, research stated, "The focus of this research lies on fundamental research to provide guidelines for the design of new nanocatalyst toward improvement of the performance of proton exchange membrane fuel cells (PEMFCs). To achieve this overarching goal, several specific steps were taken with aims to: (1) provide guidelines for the design of new catalysts; (2) promote nanocatalyst applications towards alternative energy applications; and (3) integrate advanced instrumentation into nanocharacterization and fuel cell (FC) electrochemical behavior."

Our news journalists obtained a quote from the research, "In tandem with these goals, the cathode catalysts were extensively refined to improve the performance of PEMFCs and minimize noble metal usage. In this study, the major accomplishment was producing aligned carbon nanotubes (ACNTs), which were then modified by platinum (Pt) nanoparticles via a post-functionalization colloidal chemistry approach. The Pt-ACNTs demonstrated improved cathodic catalycity, by building better device endurance and decreased Pt loading. It was also determined that surface mechanical properties, such as elastic modulus and hardness were increased. Collectively, these enhancements provided an improved FC device. The electrochemical analyses indicated that the power density of the PEMFCs was increased to 900 mW/cm(2) and current density to 3000 mA/cm(2), respectively."

According to the news editors, the research concluded: "The Pt loading was controlled at lower than 0.2 mg/cm(2) to decrease the manufacturing expenses."
