作为市场监测农药的一部分,样品由登记主管部门、登记持有人和进口许可证持有人在市场上采集并检查特性。主要问题在于样品组成是否与申请登记时一致,样品物理化学性质等技术参数是否与FAO/WHO技术标准一致。vinke(2009)对农药的特性评估进行了一次彻底的修订。最重要的是,标准描述了评估农药样品的研究结果。农药分析德语工作组(DAPA)和制剂产品分析德语工作组(DAPF)完成修订工作。

Evaluation of the Electrical contact Area at the SOFc cathode

引用

Journal of Energy and Power Engineering 2011年第5期5卷 474-479页

作者： V.A.c. Haanappel I.c. vinke L.G.J. de Haart D. Stolten Institute of Energy Research Forschungszentrum Jiilich GmbH Jalich 52425 Germany

In the frame of the ZeuS-III project, a model study was started on evaluation the area-specific resistances (ASRs) of various layers being used in SOFc stacks. It is well known that stack performance not only depends on cell resistance but also on the electrical conductivity of the various applied contact and protective layers. Various layers have been tested under simulated SOFc conditions, and results have shown that the lowest ASR value, about 3 m?·cm2, was obtained for an LSM (2) contact layer. A significantly higher resistance was found for the combined contact and protective layer Lcc10-Mn3O4, being around 37 m?·cm2. Related to the various tests, the total ASR of an F-design stack, developed by Forschungszentrum Jülich, under ideal conditions can be estimated. In this case the ASR value was calculated as the sum of that of the Lcc10-Mn3O4 layer and the formed oxide scale due to oxidation of crofer22APU. contacting resistance at the anode side was considered negligible. When differences in the ASR values occurred when compared with that from current-voltage measurements performed with real SOFc stacks, this can be explained by the limited contact area between interconnect and cathode. These results can be used to model the influence of various applied layers and different geometric contact areas on the overall ASR as determined from performance measurements with SOFc stacks.
