Abstract[English]
In a fuel cell system with a HT-PEM fuel cell (2), hydrogen is separated from the anode exhaust gas and recycled into the anode (10A) of the fuel cell (10) in order to increase efficiency. Separation of H2 gas from the anode exhaust gas leaves an option for collecting the remaining CO2 after condensing the water, with the additional aspect of using the dried remaining CO2-free anode exhaust gas for recirculation into the reformer (7) and/or the reformer heater (6). The latter is motivated by the fact that the electrochemical H2 separator (12) is only used for separating less than 90% of the H2 available H2 in the anode exhaust gas, which prolongs the lifetime of the H2 separator (12).[French]
Dans un système de pile à combustible avec une pile à combustible HT-PEM (2), de l'hydrogène est séparé du gaz d'échappement d'anode et recyclé dans l'anode (10A) de la pile à combustible (10) afin d'augmenter le rendement. La séparation du gaz H2 du gaz d'échappement d'anode offre la possibilité de collecter le CO2 restant après la condensation de l'eau, avec l'aspect supplémentaire d'utiliser le gaz d'échappement d'anode sans CO2 séché restant pour la recirculation dans le reformeur (7) et/ou le dispositif de chauffage de reformeur (6). Ce dernier aspect est motivé par le fait que le séparateur électrochimique de H2 (12) est utilisé uniquement pour séparer moins de 90 % du H2 disponible dans le gaz d'échappement d'anode, ce qui prolonge la durée de vie du séparateur de H2 (12).
