This paper discusses the possibility to use current ripple introduced by switch mode power converters for low-cost monitoring of polymer electrolyte membrane (PEM) fuel cell (FC) state-of-health, suitable commercial applications that cannot afford dedicated instrumentation. In more details, an estimate ohmic resistance, which is a good indicator water content, can be obtained from high-frequency response data processing in frequency domain, while lower at 100/120 Hz (when present) typical...
Nanocellulose-based materials are attracting an increasing interest for the positive role they could play in sustainable development; being originated from renewable resources. Moreover, cellulose has a high potential of recycling both post-consumer waste and industrial waste. Both factors, i.e., recyclability resources; results also extremely favourable perspective circular economy. Despite all these aspects, production yet to start. At lab scale, many preparation methods nanofibres (CNF)...
C OST and reliability are two key aspects that still hinder a massive-scale market diffusion of fuel cell (FC) technology.For this reason, the development low-cost diagnostic tools control systems able to guarantee reliable long-term FC operation appears as primary objective be pursued in next years.In particular, for polymer electrolyte membrane (PEM) FCs, continuous monitoring water content would extremely important, it deeply affects efficiency, voltage stability, lifetime.Indeed, an...
The intercalation of organic polymers molecules (i.e., PEGs and BRIJ) into a standard Ca-montmorillonite has been studied by XRD, TG, IR spectroscopy. polymer is confirmed the increasing d(001) in XRD spectra as well complex multisteps thermal decomposition behavior organo-clay materials. Mid-IR diffuse reflectance near-IR intercalated materials show diagnostic bands (CH stretching deformation mode), shifted or changed shape interaction with clay matrix. Both PEG 1500 4000 based are likely...
Polymer electrolyte membrane fuel cell (PEM FC) operation is likely to be characterized by voltage dips on timescales shorter than 1 s, arising from temporary flooding of gas channels or porous layers, particularly when the FC operated at high humidity levels. If supercapacitors are employed in hybrid systems, they can make up for lack energy produced FC. However, steep slopes affect that actually delivered supercapacitor because its series impedance, and this should taken into account...
As global trade continues to intensify, the role of pallets becomes increasingly crucial, as they are essential for movement goods worldwide. Wooden most common packaging type in Italy and Europe, their widespread use distribution freight transportation means that relatively minor environmental impact an individual pallet is greatly magnified by overall scale operations. The management can significantly influence both emissions costs associated with This work presents a case study...
This study investigates the potential of graphene-based additives to improve mechanical properties compacted soil mixtures in rammed-earth construction, contributing development environmentally friendly building materials. Two distinct soils were selected, combined with sand at optimized ratios, and treated varying concentrations a graphene liquid solution paste (0.001, 0.005, 0.01, 0.05, 0.1 wt.% relative soil-sand proportion). The effects these analyzed using modified Proctor compaction...
This paper analyzes possible humidity-related instabilities of polymer electrolyte membrane (PEM) fuel cell (FC) operation that affect electrochemical impedance spectroscopy measurements.The compensation ohmic resistance variations due to such instabilities, achieved using the well known multisine excitation technique with properly chosen high-frequency harmonic components, is proposed here as a new approach improve low-frequency measurements.Additionally, this method allows more accurate...
Abstract In this work, perfluoropolyether (PFPE) functionalization was used as hydrophizing treatment for gas diffusion layers (GDLs) in polymer electrolyte membrane fuel cells (PEMFCs), instead of standard PTFE coatings, aiming to enhance the hydrophobicity media and reduce mass transfer limitations final device. Carbon cloth carbon black were functionalized by decomposition a PFPE peroxide. PFPE‐functionalized employed preparation an ink suitable obtaining microporous (MPLs) deposition...
