Outline of Final Research Achievements

In this project, I aim to increase the electric power density of direct methanol fuel cells up to 120%, compared to that obtained before the project inception. I tried to use novel carbon nanomaterials including carbon nanocoil (CNC) for micro-porous layer (MPL) and catalyst support, respectively. Among the four-types of carbon nanomaterials used, CNC showed the highest performance as a catalyst support for the anode of DMFC. Consequently, the Pt-Ru-supported CNC was used in the anode catalyst layer of the DMFC. In the MPL, two carbon nanomaterials were compared. Vulcan, a commercially available carbon nanomaterial, resulted in higher power density.
In the final year of the project, the objective was achieved.
