Advanced Electro-Catalysts through Crystallographic Enhancement

Gang Wu Lab

Novel large-sized (up to 1000 nm) graphene tubes being robust and active support for Pt catalyst in fuel cells

NGTs are used as an advanced support to boost Pt cathode performance for proton exchange membrane fuel cells, which holds great promise to meet the US DOE 2020 metric targets for fuel cell vehicle applications. 

Overview

In this project, the Gang Wu lab at the University at Buffalo is collaborating with  Los Alamos National Laboratory, Brown University and the University of Pennsylvania, to develop a new type of high-surface-area and large size nitrogen-doped graphene tube (NGTs) support. NGTs are used as an advanced support to boost Pt cathode performance for proton exchange membrane fuel cells, which holds great promise to meet the US DOE 2020 metric targets for fuel cell vehicle applications. This project is supported from U.S. DOE Energy Efficiency & Renewable Energy (EERE), Fuel Cell Technologies Office.
