What a filter tip’s filtration effect exactly is and what the relationship between the filtration effect and materials used, and what the relationship between the filtration effect and the length of the filter is are three problems worthy to be studied.
What is the relationship between the filtration effect and materials used?
But the absorption rate of a filter is decided by the filter materials.

Investigation of Cobalt-free Cathode Material Ba0.5Sr0.5Fe0.8Cu0.2O3−δ for Micro-tubular SOFC with Asymmetric Structure Anode Xiaozhen Zhanga, Yongqing Wang, Jing Zhang, Qibing Chang, Yuhua Jiang, Jian-er Zhou School of Material Science and Engineering, Jingdezhen Ceramic Institute, Key Laboratory of Jiangxi Universities for Inorganic Membranes, Jiangxi Key Laboratory of Advanced Ceramic Materials, Jingdezhen 333001, P.R.
Therefore, remarkable efforts have recently been made to the development of alternative cathode materials with high electrochemical performance in order to reduce the operating temperature of the SOFCs to an intermediate temperature range (below 800°C).
Recently, a novel cobalt-free perovskite oxide Ba0.5Sr0.5Fe0.8Cu0.2O3−δ (BSFCu) has been reported to be potential cathode materials for intermediate temperature SOFCs with advanced electrochemical properties [10].
