Figure 1: Nyquist plots and deconvolution spectra for Cell 2 at two temperatures and three flows: (A) Normal, (B) low air, (C) low fuel. (a) Nyquist plots at 800 ºC. (b) Deconvolution spectra at 800 ºC. (c) Nyquist plots at 700 ºC. (d) Deconvolution spectra at 700 ºC. Nyquists plots are corrected for ohmic resistance and inductance. Deconvolution ordinates are the product of the deconvolution values and the polarization resistance.
Figure 2: Infiltration of manufacturer’s cells resulted in Area Specific Resistance (ASR) decrease of more than 20% and power density increase of more than 30%. Tests on the manufacturer’s cells were consistent or better than the average results obtained on all cells tested at NETL using the infiltration technology.
