Abstract

Abstract : Water management in the cathode is one of the most significant issues in proton exchange membrane fuel cells, especially for long-term stability and dynamic operation in fuel cell vehicles. Therefore, it is critical to design a water-managed/well-fueled cathode layer to overcome significant mass transfer limitations and the corrosion of the carbon support in fuel cells. In this work, we report a simple modification method of the Pt/C cathode using highly graphitized carbon nanofibers for improved water management. This study may open up new possibilities for water management and will be helpful for developing high performing proton exchange membrane fuel cell.
