Patent

CA 2368891

The invention relates to a PEM or a PAFC fuel cell battery with a heating element and improved cold start performance. The invention also relates to a method for cold-starting such a battery. The heating element, e.g. a wire, heats a minimal area of a fuel cell unit. The entire battery can then be autothermally heated up starting at said area.

L'invention concerne une batterie de piles à combustible PEM ou PAFC à élément de chauffage et à propriété améliorée de démarrage à froid, ainsi qu'un procédé pour le démarrage à froid d'une telle batterie, caractérisé en ce que l'élément de chauffage, par exemple, un fil métallique, chauffe tout d'abord une région minimale d'une unité de pile à combustible, région à partir de laquelle il devient alors possible de produire un chauffage élevé autothermique de toute la batterie.
