[null,null,null,"Sommario/riassunto","The proton exchange membrane fuel cell is an electrochemical energy conversion device, which transforms a fuel such as hydrogen and an oxidant such as oxygen in ambient air into electricity with heat and water byproducts. The device is more efficient than an internal combustion engine because reactants are directly converted into energy through a one-step electrochemical reaction. Fuel cells combined with water electrolyzers, which electrochemically split water into hydrogen and oxygen using renewable energy sources such as solar, mitigate global warming concerns with reduced carbon dioxide emissions. This collection of papers covers recent advancements in fuel cell technology aimed at reducing cost, improving performance, and extending durability, which are perceived as crucial for a successful commercialization. Almost all key materials, as well as their integration into a cell, are discussed: the bus plates that collect the electrical current, the gas diffusion medium that distributes the reactants over catalysts promoting faster reactions, and the membrane separating oxygen and hydrogen gases and closing the electrical circuit by transporting protons. Fuel cell operation below the freezing point of water and with impure reactant streams, which impacts durability, is also discussed."]

[null,null,null,"Sommario/riassunto","La LSF est la langue gestuelle parlée par les Sourds de France. Longtemps interdite, elle a été reconnue en France en 2005, un CAPES de LSF a été créé en 2010, elle est enseignée de l’école primaire à l’université. La LSF – comme toutes les langues gestuelles du monde – obéit aux lois de la gestualité : imiter le réel (ce que l’on nomme « iconicité ») et inscrire son corps dans l’espace (ce que l’on nomme « spatialité »). Elle met en œuvre, par le canal visuo-corporel, les facultés de langage humaines. En ce sens, elle possède des caractéristiques propres, mais, en tant que langue parmi les langues, on peut aussi l’analyser avec les outils que la linguistique générale a forgés depuis plus d’un siècle. Cet ouvrage de référence, présentant de nombreux exemples et schémas ainsi que de nombreuses illustrations, est le premier qui propose d’explorer et d’expliquer le fonctionnement linguistique de la LSF en regroupant des analyses concernant le lexique, la morphologie et la syntaxe."]
