Consequences for the aviation market in Russia's aggression against Ukraine

Journal of Modern Science, 2023
The Russian invasion of Ukraine has led to the closure of airspace in the conflict area. This has resulted in the closure of some routes and also cut off Russia's national carrier. European Union sanctions also affect the supply of aircraft parts.

Multifunctional Matrix‐Activated Electrodes Enabling Efficient Proton Transport and Durable Low‐Pt Operation for High‐Temperature Proton Exchange Membrane Fuel Cells

Advanced Energy Materials, EarlyView.
This work introduces a CeHP‐enabled multifunctional matrix‐activated electrode (MME) for high‐temperature PEM fuel cells, forming an electrochemically and mechanically functional matrix within the catalyst layer. The design increases peak power density by 38% and reduces voltage decay by 62% at 240 °C, while using only 40% of the Pt loading of a ...
