| Outline of Final Research Achievements |
To understand and control transport phenomena of reactant gas, electron, ion and generated water in polymer electrolyte fuel cells is key to have a higher performance device. In this study, the concept of a single-layer electrode was suggested to have the highest oxygen gas and generated water transport properties in the system. The performance evaluation in channel and rib scale resolution was conducted. In-situ measurement technique of gas transport properties in the electrode was developed and demonstrated the measurement. Additionally, rheological measurement of electrode slurries was conducted to design and fabricate well-ordered electrode structure.
