Hybrid Ionomer‐Free Porous Transport Electrodes With Catalyst Coated Membranes for Enhanced Water Electrolysis

open access: yesAdvanced Energy Materials, EarlyView.
We demonstrate how improved electrochemical performance during water electrolysis is achieved when a porous transport electrode (PTE) is coupled with a traditional catalyst coated membrane (CCM). Using operando neutron radiography, a more homogenous water distribution near the catalyst layer‐membrane interface is revealed in PTE‐based designs due to ...

Analysis of PEM electrolyzers [PDF]

open access: yes, 1998
Hydrogen and oxygen can be produced using a PEM electrolyzer. A PEM electrolyzer operates like a fuel cell in reverse. On the anode side of the electrolyzer, electrons are removed from water to form protons and oxygen molecules. The protons are then transported across the membrane. The protons then rejoin with electrons to form hydrogen molecules.

Impact of Environmental Weathering on the Chemical Composition of Spilled Oils in a Real Case in Brazil

open access: yesCoasts
Brazil suffered the largest oil spill disaster in its history, beginning on August 2019, affecting the Northeast coast. This study proposes a chemical investigation of oils from the 2019 spill in Brazil, which had naturally undergone different weathering

Nonlinear Model Predictive Control applied to Transient Operation of a Gas Turbine

open access: yesJournal of Sustainable Development of Energy, Water and Environment Systems, 2018
This work aims to investigate the application of a comprehensive nonlinear model-based predictive control strategy as a means to avoid unsafe or inappropriate operation of a gas turbine. Herein, the nonlinear model-based predictive control is employed to

Working with laws, regularities and singularities in biology: The evolution of mammalian red blood cell size as a case study

open access: yesThe Anatomical Record, EarlyView.
Abstract Phylogenetic comparative methods have been used in recent literature to work with laws and test for regularities (evolutionary associations of quantitative features) and evolutionary singularities (features that evolved in a single taxon). We analyzed these uses epistemologically, taking the evolution of red‐blood‐cell mean corpuscular volume (

Biogas in PEM-Brennstoffzellen

open access: yes, 2005
Die Nutzung von Biogas in Brennstoffzellen kombiniert vorteilhaft eine kostengünstige regenerative Energiequelle mit einer Technologie, die hohe Wirkungsgrade und Umweltverträglichkeit verspricht. Erstmalig wird die Eignung von Polymer-Elektrolyt-Membran- Brennstoffzellensystemen (PEMFC) zur Verstromung von Biogas experimentell nachgewiesen.

‘They Even Have the Capacity, but the Places Aren't Prepared to Receive Them’: Community Environment and Participation of Autistic Children in a Family‐Engaged Research Analysis

open access: yesAutism Research, EarlyView.
ABSTRACT To examine the associations between community environmental barriers and support and the participation of autistic children, and to interpret these findings from the perspective of caregivers engaged as research partners. This cross‐sectional observational study employed a mixed‐methods design.

Green Hydrogen for Public Transportation: Insights From an ABM and From Palma de Mallorca Case Study

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The development of green hydrogen (GH2) value chains is crucial for decarbonizing sectors such as transport and industry. Their emergence, however, requires coordination among diverse actors, technologies, and regulations, which traditional analytical approaches struggle to capture.
