本研究旨在用水阿基米德斯法测量固体氧化物燃料电池阳极的孔隙率。有多种替代能源可以替代化石燃料电池，如核能、风能、太阳能、生物燃料以及地热和燃料电池。在所有化石燃料的替代品中，有一种能源生产形式脱颖而出，有望实现可持续的未来能源，那就是燃料电池。此外，与其他形式的能源发电相比，它提供了许多优势。提出了一种用于水浸孔隙度测量的阿基米德方法。有些结果超出了合理的限度，给出了负的孔隙率，有时甚至超过了100%。这些不可接受的结果的原因要么是水进入样品，要么是样品由于保持膜中的空气而变得浮力。由于与结果相关的误差，阿基米德孔隙度测量的结果只能定性地使用。还需要指出的是，阿基米德孔隙法并不是测量涂层样品孔隙率的理想技术。建议对较大的样品进行分析，以帮助将称重误差降至最低。
The present research is aimed to measure the porosity of anodes in solid oxide fuel cell through water Archimedeans method. There are various alternatives available to replace fossil fuel cells like nuclear power, wind energy, solar energy, bio fuel, and geothermal and fuel cells. Among all the alternatives of fossil fuel, one form of energy production that stands out from the rest and promises a sustainable future energy is fuel cell. Moreover, it offers many advantages in contrast to other forms of energy generation. An Archimedean approach for water immersion porosimetry is carried out. Some of the results are beyond rational limits, and given negative and sometime above 100 percent porosity. The reasons for these unacceptable results are either due to water ingress into the sample or the sample turns into buoyant due to air in the cling film. The results from Archimedean porosimetry should only be used qualitatively due to errors associated with the results. It is also noted that Archimedean porosimetry is not the ideal technique for measuring the porosity of coated samples. It is suggested that larger samples should be analyzed that will help to minimize the weighing errors.
