  • the poisoning inhibits the chemical reaction between the reactant and the protons, thereby reducing the electrical cell voltage between the electrode and the counter electrode.
  • the layer thickness of the electrode is less than 100 microns.

  • the electrode is preferably made of palladium or a palladium / silver alloy.
  • hydrogen can be used as the fuel.

Abstract

L'invention concerne une pile à combustible (1) qui présente un substrat (2) comportant une ouverture de passage (10) et un empilement de couches (7) disposé sur le substrat (2). Cet empilement de couches comporte une électrode (3) réalisée sous la forme d'une membrane métallique autoporteuse, recouvrant l'ouverture de passage (10), qui est perméable aux atomes d'hydrogène et bloque le passage de combustible gazeux ou liquide, une contre-électrode (6) et une couche d'électrolyte (4) qui est perméable aux protons, est disposée entre l'électrode (3) et la contre-électrode (6) et est adjacente à un matériau catalytique. Pour assurer l'apport d'un combustible contenant des protons, la pile à combustible (1) présente un dispositif de mise à disposition de combustible (14) qui est relié à l'électrode (3) par l'intermédiaire de l'ouverture de passage (10). Pour assurer l'apport d'un réactif, un dispositif de mise à disposition de réactif (15) est relié à la couche d'électrolyte (4) par l'intermédiaire de la contre-électrode (4). Le réactif est apte à réagir avec les protons pour générer du courant. L'épaisseur de couche de l'électrode (3) est inférieure à 1 µm et l'électrode (3) est constituée sur toute son épaisseur d'un matériau non poreux.
