Title (EN) FUEL CELL BYPASS DIODE STRUCTURES AND ATTACHMENT METHODS
(FR) STRUCTURES DE DIODES DE DÉRIVATION POUR PILES À COMBUSTIBLE ET PROCÉDÉS DE FIXATION
Abstract:
(EN) A fuel cell system includes a fuel cell stack which includes a plurality of fuel cells contacted in series by a plurality of interconnects. The various embodiments provide systems and methods for coupling a fuel cell stack with an electric bypass module within a hot zone. The bypass module may include elements for conducting a current between interconnects in a fuel cell stack and thereby bypass a failed fuel cell that has become a resistive parasitic load.
(FR) L'invention concerne un système de pile à combustible comportant un bloc de piles à combustible comprenant une pluralité de piles à combustible raccordées en série par une pluralité d'interconnexions. Les divers modes de réalisation concernent des systèmes et des procédés destinés à coupler un bloc de piles à combustible à l'aide d'un module de dérivation électrique au sein d'une zone chaude. Le module de dérivation peut comprendre des éléments servant à conduire un courant entre des interconnexions dans un bloc de piles à combustible et à contourner ainsi une pile à combustible défaillante qui est devenue une charge résistive parasite.
