Abstract: This work aimed to improve the performance of proton exchange membrane fuel cell (PEMFC) through two approaches. One is to improve the methods of fabricating membrane-electrode-assembly. Four different methods were compared. The various aspects of the fabrication have been discussed in details, including the composition, thickness and porosity electrodes, and the compaction force. By optimizing the fabrication parameters the performance of the fuel cell has been enhanced by >50%. The second approach is the application of citric acid modified carbon nanotubes as catalyst support for PEMFC. The novel catalyst materials demonstrated better performance compared to catalyst supported on commercial carbon blacks in methanol oxidation and PEMFC testing. The experimental studies demonstrated that the performance depends on electrochemical properties of the catalyst and the physical structure of the electrodes and the performance of PEMFC can be further improved through research on both advanced nano-scale materials and advanced fabrication techniques.
