Journal ArticleDOI
Preparation and characterization of nano-sized phase change emulsions as thermal energy storage and transport media
Junren Chen,Pengfei Zhang +1 more
TL;DR: In this paper, the phase change emulsion (PCE) is used as both the thermal energy storage material and transport medium simultaneously in a thermal storage system, and the results suggest that the PCEs show a drastic reduction of pumping power compared with water at the same heat storage capacity.
Journal ArticleDOI
Effect of clamping pressure on liquid-cooled PEMFC stack performance considering inhomogeneous gas diffusion layer compression
TL;DR: In this paper, a numerical study was performed to investigate the effect of clamping pressure on the performance of liquid-cooled PEMFC stacks, which can be utilized as a guidance for stack assembly process in practical application.
Journal ArticleDOI
Pulverization, expansion of La0.6Y0.4Ni4.8Mn0.2 during hydrogen absorption-desorption cycles and their influences in thin-wall reactors
TL;DR: In this article, the pulverization, expansion, and strain of La 0.6 Y 0.4 Ni 4.8 Mn 0.2 and their influences in horizontal and vertical thin-wall reactors were investigated.
Journal ArticleDOI
Insight into the Rapid Degradation Behavior of Nonprecious Metal Fe-N-C Electrocatalyst-Based Proton Exchange Membrane Fuel Cells.
Junren Chen,Xiaohui Yan,Cehuang Fu,Yan Feng,Chen Lin,Xiaolin Li,Shuiyun Shen,Changchun Ke,Junliang Zhang +8 more
TL;DR: Results indicate that Fe at active sites of catalysts is attacked by hydroxyl free radicals decomposed from H2O2 which is further leached out, causing an increase in activity loss, and it is assumed that the quick performance loss of Fe-N-C based fuel cell is caused by water flooding within catalyst layer, which is proved to be incorrect in this study.
Journal ArticleDOI
Properties of La0.2Y0.8Ni5−xMnx alloys for high-pressure hydrogen compressor
TL;DR: In this article, Veziroglu et al. investigated the absorption/desorption properties of two alloys, La(0.2)Y (0.8)Ni(5-x)Mn(x) (x = 0.3, 0.4), for high-pressure hydrogen compression application and found that Mn could lower the plateau pressure effectively, improve the hydrogen storage capacity and absorption kinetics but slightly increase the slope of the pressure plateau and hysteresis.
