Show abstractHide abstract

It is estimated that approximately 50% of a data center's total energy requirement is dedicated for cooling. Therefore, reducing a data center's cooling system power consumption would actually result in a significant reduction in overall power consumption. In this paper, more detailed models and design considerations for a heat pipe based ice storage system for data center cooling are presented. A variation of this configuration, as well as a combination of the existing and proposed methods are also presented. Finally some cost comparisons and considerations are also presented.

This study investigates the effects of carbon fiber directions of anisotropic GDL on the performances of the PEM fuel cells. The performance is measured using a single cell with an active area of 25 cm2. The results show that the efficiency of the cell is better when the fiber direction is in perpendicular to the channel flow direction. Furthermore, a small cell with an active area of 2 cm2 is used to observe the difference of the water distribution inside the GDL, in the form of ice by freezing the temporal water distribution. The measurement and the observation results provide the difference in water distribution due to the fiber direction.
