Abstract
(EN)
An apparatus and method for determining a combustion state includes a catalytic combustion unit for mixing an anode off-gas discharged from a fuel pole of a fuel cell and an oxidizing agent gas, and having a catalytic unit for performing combustion processing. An upstream temperature detecting unit detects a gas temperature at an upstream side of the catalytic unit, and a gas-phase combustion determining unit compares at least one of the gas temperature detected by the upstream temperature detecting unit and a rate of upstream temperature increase with a determining reference value to determine if gas-phase combustion occurs at the upstream side of the catalytic unit.
(FR)
L'invention concerne un appareil et un procédé destinés à déterminer un état de combustion qui comprend une unité de combustion catalytique servant à mélanger un gaz d'échappement d'anode déchargé d'un pôle combustible d'une pile à combustible et d'un gaz d'agent oxydant, et possédant une unité catalytique destinée à mettre en oeuvre un traitement par combustion. Une unité de détection de température en amont détecte une température gazeuse au niveau du côté amont de l'unité catalytique, et une unité de détermination de combustion en phase gaseuze compare au moins une température gazeuse détectée par l'unité de détection et un taux d'augmentation de température en amont avec une valeur de référence déterminante en vue de déterminer si la combustion en phase gazeuse a lieu au niveau du côté amont de l'unité catalytique.
