Definitions

  • the invention relates to a method for operating a fuel cell arrangement with a number of fuel cells arranged in a protective housing. It further relates to such a fuel cell arrangement.
  • Fuel cells can be used for the environmentally friendly generation of electricity.
  • a process takes place in a fuel cell that essentially represents a reversal of electrolysis.
  • a hydrogen-containing fuel is supplied to an anode and an oxygen-containing auxiliary to a cathode.
  • the a-node and cathode are electrically separated from one another via an electrolyte layer, the electrolyte layer permitting ion exchange between the fuel and the oxygen, but otherwise ensuring a gas-tight separation of fuel and auxiliary material.
  • hydrogen contained in the fuel can react with the oxygen to form water, electrons accumulating on the fuel-side electrode or anode and electrons being taken up on the auxiliary-side electrode or cathode.
  • the electrolyte layer which can be formed as a ceramic solid electrolyte in a high-temperature fuel cell or as a polymer membrane in a low-temperature fuel cell, thus has the function of separating the reactants from one another, converting the charge in the form of ions and unifying To prevent electron shorting.

  • the gas atmosphere located in the interior 6 enclosed by the protective housing 4 is replaced at least partially or continuously by fresh gas F at maintenance intervals.
  • undesirable impurities and components which are particularly disadvantageous for the durability and operational reliability of the fuel cell arrangement 1, such as in particular water and molecular hydrogen, are removed from the atmosphere from the interior 6.
  • An accumulation of the substances mentioned, which in turn could lead to corrosion or impairment of the functionality of individual components arranged in the interior 6, is thus ruled out even during a long operating time.

Abstract

L'invention concerne un procédé permettant de faire fonctionner un ensemble de piles à combustible et un ensemble de piles à combustible pour la mise en oeuvre de ce procédé. L'objectif de l'invention est que l'on puisse faire fonctionner un ensemble de piles à combustible (1), comportant une pluralité de piles à combustibles disposées dans un logement protecteur (4), avec une fiabilité de fonctionnement élevée et une longévité particulièrement grande. A cet effet, il est proposé, selon l'invention, qu'au moins une partie du gaz se trouvant dans l'espace intérieur (6) défini par le logement protecteur (4) soit évacuée de cet espace intérieur (6) et remplacée par du gaz frais.
