| Outline of Final Research Achievements |
This research was conducted to clarify and demonstrate the design solution of the porous electrode called catalyst layer, that minimizes the energy loss in the polymer electrolyte fuel cell. Considering electrode materials and voids in the catalyst layer and their volume fractions, a three-dimensional reaction transport structure model with the two-phase flow behavior was developed, and the design factors and energy loss of the electrode catalyst layer were investigated. For the demonstration, we developed the microprinting technology and carried out cross-section analysis and thermal analysis measurement to clarify the mechanism by which the porous structure was different in the microprinting catalyst layer and the cell performance was improved. We have acquired the structural analysis method and structural control technology that are the basis for elucidating and demonstrating the design solution of the fuel cell electrodes for the minimization of energy loss.
