Hydrogen Gas Diffusion Influences Cavity Pressure of Encapsulated Inertial Sensors

Kopf, Marlene; Mogor-Györffy, Robert; Breitling, Achim - 2022

MEMS inertial sensors are oscillatory electro-mechanical devices that detect relative motion in an inertial frame. Frictional losses in these systems, expressed as a quality factor Q , directly have bearing on their absolute measurement accuracy, and hence on the duration of an acceptably...

Elucidating the Role of Alkyl Chain in Poly(Aryl Piperidinium) Copolymers for Anion Exchange Membrane Fuel Cells

Hu, Chuan; Park, Jong Hyeong; Kim, Hae Min; Bae, Joon Yong - 2022

Poly(aryl-co-aryl piperidinium) (c-PAP) has recently attracted wide attention in anion exchange membrane (AEM) fuel cells (AEMFCs). Here, we report poly(aryl-co-terphenyl piperidinium)-x (PDnTP-x) AEMs with different alkyl spacers(n=0, 1, 2, 6, 10) in the backbone. Long alkyl chains (n=6 or 10)...

Highly Stable Nanocarbon Supported Pt Catalyst for Fuel Cell Via a Molten Salt Graphitization Strategy

Luo, Yi; Feng, Junzong; Wang, Lukai; Jiang, Yonggang; … - 2022

Proton exchange membrane fuel cells (PEMFCs) durability has been severely hindered by poor stability of carbon support in the cathodic Pt-based catalyst. Herein, a high-surface-area nitrogen doped graphitic nanocarbon (N-G-CA) with mesopores is developed as Pt support to address PEMFCs...
