Feed‐Forward PID‐Based Cooperative Control Strategy for Air Mass Flow and Pressure in PEMFC Systems

open access: yesEnergy Science &Engineering, EarlyView.
This manuscript presents an 86 kW proton exchange membrane fuel cell (PEMFC) with a feed‐forward PID control strategy, tested in an engine environment. The air mass flow and pressure changes are analyzed across three stages: loading, de‐loading, and wide range of sudden load drop. Experimental results demonstrate the control strategy's effectiveness of

Magneto‐Hydrothermal and Entropy Analysis of Double‐Diffusive Convection in a Nano‐Encapsulated PCM‐Suspended Elliptical Pipes Thermal Storage Tank: Impact of Exothermic Reaction

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT PCMs store thermal energy during phase transitions without temperature changes, making them valuable for various thermal applications. When direct PCM use isn't practical, researchers have developed encapsulation methods as an alternative approach.

Analysing the Drivers of Cropland Footprint in Leading Agricultural Nations: Evidence From MMQR Approach

open access: yesGeological Journal, EarlyView.
ABSTRACT Climate change represents the biggest current challenge for us and for future generations. Its impact on agriculture is undeniable, considering the food security goal. Thus, the cropland footprint has been distinguished as a comprehensive index for assessing the impact of environmental changes in agricultural areas determined by the increased ...

Partnerships Supporting Young People to Negotiate Complex Pathways From School

open access: yesJournal of Adolescence, EarlyView.
ABSTRACT Introduction The school‐to‐work transition (SWT) is complex for young people. The postpandemic era, characterized by rapidly evolving economies and technologies, has augmented the complexity of negotiating such pathways. Despite this, young people—understood here through the lens of emergent adulthood—are often positioned as wholly responsible
