Experimental study on the self-humidification effect in proton exchange membrane fuel cells containing double gas diffusion backing layer

Experimental study on the start-up with dry gases from normal cell temperatures in self-humidified proton exchange membrane fuel cells

“…However, at the same time, the excess water accumulated in the cell is removed by supplied gases during operation. Therefore, if the dry reactant gases are oversupplied, the membrane can't absorb sufficient water and dry out problem occurs [32]. In addition, as the cell temperature increases, the produced water easily evaporates and the membrane is dehydrated rather than hydrated.…”

A capacity model based on charging process for state of health estimation of lithium ion batteries

“…4. 1 The IC curve (blue solid line) derived from the proposed capacity model captures all the four peaks. Compared to the IC curve (red dashed line) obtained using numerical derivation under dV ¼ 2:5 mV from the voltage vs. charged capacity curve, it is much smoother.…”

“…Energy crisis and environmental concerns are urgent problems to be solved for world's sustainable development [1][2][3]. Lithium ion batteries (LIBs) can be used both on static energy storage and transportation energy storage [4,5] thanks to their remarkable advantages such as high specific energy, high efficiency, and long life [6,7].…”

Latest Trends and Challenges In Proton Exchange Membrane Fuel Cell (PEMFC)

“…GDL with hydrophilic layer shows high performance as compared to conventional GDL. Kong, et al [19] focused their studies in self-humidification result in PEMFCs. Uniform organized GDL and heterogeneous organized GDL utilized for the experiment purpose.…”
