Title
(EN) CONTROL ARRANGEMENT AND METHOD FOR ADAPTING A FUEL CELL SYSTEM TO FUEL COMPOSITION
(FR) AGENCEMENT DE COMMANDE ET PROCÉDÉ POUR ADAPTER UN SYSTÈME DE PILE À COMBUSTIBLE À UNE COMPOSITION DE COMBUSTIBLE
Abstract
(EN)
An object of the invention is a control arrangement, which comprises means (120) as a first control mechanism for determining assumed inlet fuel composition information, means (122) for determining predicted cell voltage information, and means (124) for determining a correction term to the assumed inlet fuel composition information based on the difference between said measured cell voltage information and said predicted cell voltage information. The control arrangement comprises at least one superposed control mechanism (126, 128) to the first control mechanism for performing at least mainly tuning type control operations, which have a distinct time constant between control operations compared to the control operations of the first control mechanism, said tuning type control operations being performed for matching the assumed inlet fuel composition information to the real fuel composition during start-up or operation of the fuel cell system.

L'invention concerne un agencement de commande qui comprend des moyens (120) servant de premier mécanisme de commande pour déterminer des informations de composition de combustible supposée à l'orifice d'entrée, des moyens (122) pour déterminer des informations de tension de pile prévue, et des moyens (124) pour déterminer un terme de correction par rapport aux informations de composition de combustible supposée à l'orifice d'entré, sur la base de la différence entre les informations concernant la tension de pile mesurée et les informations concernant la tension de pile prévue. L'agencement de commande comprend au moins un mécanisme de commande superposée (126, 128) destiné au premier mécanisme de commande, afin d'effectuer au moins principalement des opérations de commande de type réglage, qui ont une constante de temps distincte entre des opérations de commande par comparaison avec des opérations de commande du premier mécanisme de commande, lesdites opérations de commande de type réglage étant exécutées pour la mise en correspondance des informations concernant la composition de combustible supposée à l'orifice d'entrée et de ladite composition de combustible réelle, pendant le démarrage ou le fonctionnement du système de pile à combustible.
