| Outline of Final Research Achievements |
The objective of the study was to improve the PEFC performance with newly proposed hybrid GDL, in which different wettability areas were alternately arranged. It was shown that the apparent oxygen diffusivity was increased by using hybrid GDL in comparison with the normal GDL, elucidating the characteristics by the simultaneous measurement of oxygen diffusivity and visualization of water distribution by X-ray tomography. On the basis of those results, the improvement of the actual PEFC with parallel gas channels of 200 mm long was achieved with the combination of hybrid GDL and microgrooves in gas channels.
