Abstract: The present invention relates to a reverse osmosis filter module including an improved feed spacer, and particularly, to a reverse osmosis filter module including an improved feed spacer which has an asymmetric diameter in an intersection in which a first set of filaments and a second set of filaments intersect, thereby reducing differential pressure by increasing a cross-sectional area of a flow path, and mitigating concentration polarization by developing a swirl flow.

Abstract: The present invention relates to a reverse osmosis filter module including an improved feed spacer, and more particularly, to a reverse osmosis filter module including an improved feed spacer, in which spiral filaments are repeatedly positioned to form the feed spacer, such that a flow of a liquid to be supplied to the feed spacer is concentrated on a surface of a reverse osmosis membrane to effectively mitigate concentration polarization.

Abstract: A fuel cell stack structure in which unit cells are stacked includes first window frames and second window frame. The second window frames each have an area larger than an area of a first window frame and are periodically disposed at a predetermined interval in a direction in which the unit cells are stacked. Heat movement is promoted, a temperature deviation in the fuel cell stack structure is mitigated, and a temperature distribution is uniformized.
