Title (EN) CONTROL DEVICE FOR FUEL CELL SYSTEM AND RELATED METHOD
(FR) DISPOSITIF DE CONTROLE POUR SYSTEME DE PILE A COMBUSTIBLE, ET PROCEDE CONNEXE
Abstract: front page image
(EN)A control device for a fuel cell system (2) having a fuel cell stack (11) with an oxidizing electrode (11b) supplied with oxidizing gas and a fuel electrode (11a) supplied with fuel gas to generate an electric power is disclosed having an estimating section (13) estimating occurrence of a water-clogging phenomenon wherein condensed water stays in a fuel gas flow passage (HL, HL') through which fuel gas is supplied to the fuel electrode of the fuel cell stack, and a control section (14) controlling a fuel gas exhaust valve (26), which is disposed downstream of the fuel cell stack to allow the fuel gas to be exhausted from the fuel cell stack, to be brought into an opened condition when the estimating section estimates the occurrence of the water-clogging phenomenon.
(FR)L'invention concerne un dispositif de contrôle pour système de pile à combustible (2) comprenant une colonne de piles à combustible (11) à électrode d'oxydation (11b) qui reçoit un gaz d'oxydation et électrode de combustible (11a) qui reçoit un combustible pour la production d'énergie électrique. Ce dispositif comporte une unité d'estimation (13) de l'occurrence d'une occlusion à l'eau condensée dans un passage d'écoulement de gaz (HL, HL') vers l'électrode de combustible, et une unité de contrôle (14) de vanne d'évacuation de gaz (26), en aval de la colonne pour l'évacuation du gaz, passant à l'état ouvert lorsque l'unité d'estimation estime l'occurrence d'occlusion susmentionnée.
