بازسازی و تجزیه و تحلیل لایه های انتشار گاز در سلول های سوختی با استفاده از فاصله فایلی به جای اندازه های اندازه پراش: روایی مورد نظر از مدل هدایت گرمائی مبتنی بر تخلخل به طور گسترده استفاده شده

The present study clearly demonstrates that the traditional notion that fibrous materials with lower porosity have higher thermal conductivity does not necessary hold. In addition, it is shown that GDLs with the same porosity and the same pore size may have different fiber spacing and thus, distinct properties. It is found that the thermal conductivity models based solely upon porosity can be off by several hundred percent and must be either discarded or used over the narrow range of conditions under which they have been formulated.
