Investigation of Shorting by Penetration in Pem Fuel Cell Membranes
Electrical shorting through the proton exchange membrane (PEM) is a form of early failure commonly found in PEM fuel cells. In order to improve the durability and thus the commercial potential for PEM fuel cells, this form of failure must be understood and mitigated. This research investigates …

Integration of III-V optical devices and interconnects on Si using SiGe virtual substrates
… provides the promise for the combination of electrical and optical devices onto a Si platform. Monolithic integration, compare to hybrid integration, is the more cost effective and reliable way to combine these dissimilar materials. However, materials compatibility issues such as lattice …

Electrochemomechanical fatigue and fracture in electrode and electrolyte materials for Li-Ion batteries
… vulnerable to fracture-assisted internal electrical shorting, an issue that currently limits commercialization of ASSBs. We built on these results with finite element modeling of electrolyte fracture in ASSBs, thus finding a strong dependence of fracture conditions on both electrolyte …

Experimental Studies on the Mechanical Durability of Proton Exchange Membranes
… PEMs in the out-of-plane direction and cause electrical shorting. In this study, GDM samples sealed with an impermeable Kapton® film on the surface were compressed with uniform air pressure and the nonuniform displacement field was measured with a three-dimensional digital image correlation …

On the identification and mitigation of life-limiting mechanisms of ionic liquid ion sources envisaged for propulsion of microspacecraft
… by two critical challenges: electrochemistry and electrical discharges. Electrochemistry-chemical reactions between the source emitter and the ionic liquid-has been shown to be capable of fully deteriorating the source in fewer than 100 h. Electrical discharges, on the other hand, can cause source …
