| Outline of Final Research Achievements |
The objective of this study was to obtain design guidelines for the structures of the electrodes using a carbon-free connected nanoparticle catalyst, which is necessary to achieve high-power polymer electrolyte fuel cells (PEFCs). In this study, the structural control of the microporous layer (MPL) was conducted for efficient water transport from the carbon-free catalyst layer to a gas diffusion layer. In addition, the effects of the MPL structures on the fuel cell performances in the high current density region were clarified. Furthermore, this study demonstrated the structural control of the carbon-free catalyst layer by a new method using latex particles as templates. Thus, this study has succeeded in systematically controlling the electrode structures and provided useful knowledge for realizing high-power PEFCs.
