The master batch for molding includes at least one inorganic powder, advantageously ceramic or metallic; an organic mixture, advantageously polymer, comprising: a stable polymer having good ductility features, from 30 to 90% by mass of the mixture; a lubricant, from 5 to 30% by mass of the mixture; a plasticizing polymer, from 5 to 30% by mass of the mixture; with a [% by mass of the lubricant]/[% by mass of the stable polymer] ratio smaller than or equal to 1, advantageously strictly smaller than 1.

Master batch for ceramic- or metal-powder injection-molding, and method for preparing said master batch

A fuel cell element including an assembly of a membrane, a first electrode, and a second electrode, and a mechanism holding the assembly together, which forms a peripheral support thereof and that includes an electrical connection and a mechanism for circulation of fluid and for supply of the fluid into the assembly.

Joint-free integrated fuel cell architecture

The invention relates to an ion/electron-conducting composite polymer membrane ('), which comprises at least two gas-tight ion-conducting polymer portions (&#x2032;) joined together directly by a gas-tight electron-conducting polymer portion (&#x2032;). It also relates to processes that enable this membrane to be manufactured, and also to a planar fuel cell core comprising it. Applications: production of planar fuel cells used for generating electrical power intended for stationary applications, transport applications and portable and transportable applications.

Ion/electron-conducting composite polymer membrane, manufacturing processes thereof and planar fuel cell core comprising it

The invention concerns an elementary cell () for a fuel cell comprising two electrodes between which an ion exchange membrane () is positioned. According to the invention, one of the two electrodes has a threaded surface carrying the ion exchange membrane (), the assembly formed by this electrode and the ion exchange membrane () being able to be assembled by screwing onto a threaded surface belonging to the other of the two electrodes. The invention also concerns a fuel cell provided with a plurality of elementary cells ().
