Effects of composite porous gas-diffusion layers on performance of proton exchange membrane fuel cell

The gas diffusion layer (GDL) is an important component of proton-exchange membrane fuel cells (PEMFCs) that participate in the interplay of the transport of different species. During the assembly of PEMFCs, mechanical pressure is applied to the solid boundary of bipolar plates to reduce the porosity of the adjacent GDL, especially under land areas. This variation in porosity...

Continuous fabrication of bio-inspired water collecting surface via roll-type photolithography

We present a continuous fabrication method to make bio-inspired water collecting surface by using roll type photolithography for potential applications to real time air monitoring system. In this study, the carapace of the stenocara beetle was mimicked to achieve water collection from air, using a molding process involving micro-/nanofabrication techniques and roll type...
