CA 2544231

The present invention relates to a system applied for the measurement of the total ohmic internal resistance of fuel cells and stack of fuel cells. The apparatus comprises an electronic load system which comprises: an input unit generating an input pulse, a driver for the control of the input pulse, a MOSFET module comprising at least one MOSFET device for the generation of a short circuit in a fuel cell, a bank of selectable resistors and a measuring circuit which comprises: a shunt for converting the fuel cell current into a voltage signal, differential amplifiers for the current and the voltage signals and a data acquisition system which receives the voltage and the current signals obtained by the differential amplifiers.

La présente invention concerne un système permettant de mesurer la résistance ohmique interne totale de piles à combustible ou de modules de piles à combustible. L'appareil comprend un système de charge électronique qui comprend: une unité d'entrée générant une impulsion d'entrée, un pilote pour la commande de l'impulsion d'entrée, un module MOSFET comprenant au moins un dispositif MOSFET pour la génération d'un court circuit dans une pile à combustible, un banc de résistances sélectionnables, et un circuit de mesure qui comprend: une shunt pour convertir en signal de tension le courant de la pile à combustible, des amplificateurs différentiels pour les signaux de courant et de tension, et un système d'acquisition des données qui reçoit les signaux de courant et de tension obtenus par les amplificateurs différentiels.
