Journal ArticleDOI
Mini- and micro-channels: influence of axial conduction in the walls
TL;DR: In this paper, a non-dimensional number quantifying the part of axial conduction in walls of a mini-micro counter-flow heat exchanger is proposed, which is shown to be a good approximation of the heat transfer coefficient.
Journal ArticleDOI
A review of PEM fuel cell durability: materials degradation, local heterogeneities of aging and possible mitigation strategies
Laetitia Dubau,Luis Castanheira,Frédéric Maillard,Marian Chatenet,Olivier Lottin,Gaël Maranzana,Jérôme Dillet,Adrien Lamibrac,Jean-Christophe Perrin,Eddy Moukheiber,Assma ElKaddouri,Gilles De Moor,Corine Bas,Lionel Flandin,Nicolas Caqué +14 more
TL;DR: In this article, the degradation mechanisms of membrane electrode assemblies (MEAs) during proton exchange membrane fuel cell (PEMFC) operation in real life (industrial stacks) were investigated.
Journal ArticleDOI
Review of the current technologies and performances of hydrogen compression for stationary and automotive applications
TL;DR: In this paper, the authors present the technical and design features of mechanical compressors, i.e., reciprocating, diaphragm, linear and ionic liquid compressors as well as innovative non-mechanical technologies specifically conceived for hydrogen applications.
Journal ArticleDOI
Degradation heterogeneities induced by repetitive start/stop events in proton exchange membrane fuel cell: Inlet vs. outlet and channel vs. land
Julien Durst,Adrien Lamibrac,Frédéric Charlot,Jérôme Dillet,Luis Castanheira,Gaël Maranzana,Laetitia Dubau,Frédéric Maillard,Marian Chatenet,Olivier Lottin +9 more
TL;DR: In this paper, the aging heterogeneities that set up during PEMFC operation in start-up and shut down conditions were investigated based on in situ measurements of local current densities, electrochemical surface area of Pt at the cathode in a segmented cell and overall CO2 generation.
Journal ArticleDOI
Carbon corrosion induced by membrane failure: The weak link of PEMFC long-term performance

TL;DR: In this article, the authors investigated the origin of the cell voltage losses during on-site 110-cell-PEMFC-stack long-term operation (12,860h i.e. 1.5 years) and showed that the decline of electrical performance is heterogeneous at the stack and the membrane-electrode assembly (MEA) scales.
