One of the great discoveries of the study is that the MSC can be used to analyze and describe the complex reactions that both phase transformation and sintering happened at same time. In addition, using both our five-parameter S-curve fitting and German's three-parameter curve fitting lead to very similar results and values of Qa. Most importantly, we cannot find satisfactory data to support the hypothesis that Qa varies linearly either with particle diameter or with initial porosity of the samples.

在利用主导烧结曲线模型分析六组实验数据过程中，发现主导烧结曲线具有拟合烧结与相变同时发生之能力，此拟合曲线中包含了四个反应，包括anatase与anatase的烧结、anatase与rutile的烧结、rutile与rutile的烧结还有anatase的相变，此四种不同的反应竟然可以只由一条主导烧结曲线描述其变化，是本研究重要的发现。

The polarization curve is not sufficient for a reliable and unique validation of a PEMFC model since different parameters can lead to an identical polarization curve. A three-step validation approach is proposed for a complete and unique validation. These three steps are:(1) validated by the global polarization curve,(2) validated by the local current density distribution curve, and (3) validated by the cathode over-potential and anode over-potential versus current density curve. The results from the comparison of four flow-fields show that the PEMFC performance of the flow-fields decreases in order by interdigitated, metal foam, pin-type and parallel.

通过PEMFC参数敏感性研究发现，PEMFC性能受多种参数的影响，这些参数可分为非敏感性参数、敏感性参数和高敏感性参数；与阳极侧参数相比，PEMFC性能对阴极侧的参数更敏感；不同参数值的组合可以得到几乎完全相同的极化曲线，因此电池的极化曲线不足以用于验证数学模型的唯一性与可靠性；为验证PEMFC数学模型的唯一性与可靠性，提出了模型验证的三步法：极化曲线验证、局部电流密度验证和阳极总过电位与阴极总过电位验证。
