Modularer multifunktionaler Brennstoffzellenstapel mit Polymer-Eektrolyt-Membranen (PEM)

摘要

A modular multifunctional fuel cell comprises a fiber-reinforced plastic end plate (1) with integrated media distribution and sensors; a current removal plate (2) with channels for media; a plastic sealing support; a polymer electrolyte membrane; a unipolar plate as a gas distributor; a fine gas distributor; a seal for the polymer electrolyte membrane cell elements; an electrically conducting gas-tight film (e.g. graphite film) with different openings for the media flow; and a seal (10) uniformly distributed over the surface. The fiber-reinforced plastic end plate mechanically stabilizes the cell and is thermally insulated from the surroundings. Preferred Features: The unipolar plate is made from graphite having a structured surface on the side facing away from the media flow. The media is air, oxygen-enriched air, hydrogen or hydrogen-rich reformate gas, deionized water or insulating oil.
