| Research Abstract |
The local temperature rise and dry-out inside MEA could lead a PEFC to severe degradation. Then, the ultra thin thermo sensor, which thickness was several micro meter, was fabricated by semiconductor manufacturing equipments, and the local MEA temperatures were measured. By the sensor, temperature near the cathode catalyst layer was measured higher than the other parts.
The influence of the temperature field on the mass transport has not been understood well, however, revealing it by only experimental methods is very difficult. Then, we have used the numerical simulation at the same time. The effect of mass transport, thermal resistances and liquid water behavior on the PEFC performance was discussed in this study.
