Abstract
(EN)
Feedstock delivery systems and hydrogen-producing fuel processing assemblies and fuel cell systems containing the same. The feedstock delivery systems include a liquid pump that draws at least one liquid feedstock from a supply and delivers at least one feed stream containing the feedstock(s) to a fuel processor, such as to the hydrogen-producing region thereof. The feedstock delivery system further includes a recycle conduit that establishes a fluid flow path for the liquid feedstock(s) from a location downstream of the pump back to a location upstream of the pump. In some embodiments, the feedstock delivery system further includes a flow restrictor associated with the recycle conduit and a pressure-actuated valve that selectively permits the recycled feedstock to bypass the flow restrictor. In some embodiments, the pump is configured to draw a greater flow rate of the feed stream from the supply than is delivered to the fuel processor.

L'invention porte sur des systèmes de distribution d'une charge d'alimentation et sur des ensembles de traitement de combustible produisant de l'hydrogène, ainsi que sur des systèmes de piles à combustible les contenant. Les systèmes de distribution de la charge d'alimentation comprennent une pompe à liquide qui entraîne au moins une charge d'alimentation liquide depuis une source d'alimentation et envoient au moins un courant d'amenée contenant la charge d'alimentation vers un processeur de combustible, par exemple, vers une région de celui-ci produisant de l'hydrogène. Le système de distribution de la charge d'alimentation comprend également un conduit de remise en circulation qui établit une voie d'écoulement de fluide pour la charge d'alimentation liquide, depuis un point aval de la pompe et, pour le retour, jusqu'à un point amont de la pompe. Selon certaines formes d'exécution, le système de distribution de la charge d'alimentation comprend également un limiteur de débit associé au conduit de remise en circulation et une soupape commandée par la pression qui permet à la charge d'alimentation remise en circulation de contourner le limiteur de débit. Selon d'autres formes d'exécution, la pompe est configurée de façon à entraîner un plus gros débit du courant d'amenée depuis l'alimentation qui est délivré au processeur de combustible.
