[Pour] les piles PEMFC, l'électrolyte est une membrane polymère ionique de type acide ; dans ce type d'électrolyte, les ions négatifs sont retenus dans la structure de la membrane. Seuls les ions hydrogène H+ sont mobiles et libres de transporter la charge positive à travers la membrane, de l'anode vers la cathode et c'est ce mouvement associé à la circulation des électrons qui est à l'origine du courant produit.  6, record 1, French, - membrane%20%C3%A9changeuse%20de%20protons

Polymer Electrolyte Fuel Cell(PEFC)... Water management in the membrane is critical for efficient performance ;the fuel cell must operate under conditions where the byproduct water does not evaporate faster than it is produced because the membrane must be hydrated.  2, record 3, English, - water%20management

Les membranes doivent [...] pouvoir retenir l'eau pour maintenir une bonne conductivité. La gestion de l'eau dans les membranes est donc un des problèmes majeurs dans la technologie de type PEM. Les facteurs qui influencent la teneur en eau dans la membrane sont le passage de l'eau à travers la pile (pour chaque proton une petite goutte d'eau est également transportée à travers la membrane) et la diffusion de l'eau produite à la cathode à travers la membrane.  2, record 3, French, - gestion%20de%20l%27eau
