| Outline of Final Research Achievements |
The accuracy of our diagnostics was improved by removing the anode term from our diagnostics equation because the polarization that originates on an anode side was much smaller than that of a cathode side. The variation of each parameter of our diagnostics was evaluated from 500 measuring under the standard operating condition. As a result, the variations of the ΔV, A1 and t1, mean the resistance polarization, the activation polarization and the diffusion polarization, were ±25%, ±5% and ±10% respectively. Therefore, our diagnostics diagnoses a deterioration when each parameter exceeds these thresholds from the initialization state. Moreover,it was clarified that the deterioration factor was different according to the place in the same electrode using the quadrisection separator with gold plate. Furthermore, it was clarified that our diagnostics was able to diagnose the degradation factor of each cell in the four cells short stack and the unit composed of 3 cells.
