Abstract

L'invention vise à assurer l'alimentation électrique d'unités de commande, d'alerte, d'éclairage et d'affichage ou similaires dans des véhicules sur rails, indépendamment du groupe moteur, tout en réduisant le poids du module d'alimentation et en améliorant la facilité d'entretien et la protection de l'environnement. A cet effet, l'unité d'alimentation électrique utilisée est un groupe à piles à combustible qui traite du méthanol. Ce groupe comprend un réservoir (3) pour l'eau désionisée ; un réservoir (2) pour le méthanol ; un évaporateur (4) pour mélanger l'eau et le méthanol ; une unité de reformage (6) pour convertir le méthanol en hydrogène et en dioxyde de carbone ; une unité d'épuration de gaz (7) servant à éliminer le dioxyde de carbone ; un groupe de plusieurs piles à combustible à membrane électrolytique (8), dans lequel l'hydrogène et un agent d'oxydation se présentant sous la forme d'air comprimé par un compresseur (14) sont acheminés et évacués ; un circuit de refroidissement (K) servant à refroidir les piles à combustible (8) ; une conduite (16) débouchant dans le réservoir (3) et évacuant l'eau de réaction ; et une conduite qui évacue le gaz résiduel résultant de la réaction dans la pile à combustible et qui est raccordée à un brûleur catalytique (5).
