dc.description.abstract | [EN] Hydrogen fuel-cell systems are one of the alternatives for the decarbonization of the transportation sector. In such systems, the usage of O-2-enriched air has the potential to improve fuel cell performance as well as to reduce degradation phenomena linked to local O-2 starvation. However, the production of an O-2-enriched air stream implies energy consumption that needs to be evaluated in the overall system efficiency. In this study, the potential of a system including polymeric membranes for O-2-N-2 separation to produce O-2-enriched air was evaluated theoretically. First, the balance of plant, including the O-2-N-2 separation membrane and a two-stage boosting system, was considered. Two sources of energy recovery were identified: a high-pressure H-2 stream and retentate flow (N-2-rich) at the outlet of the separation membrane. Then, the efficiency of the system was evaluated for different levels of O-2 enrichment, with sensitivities to the main operational and design parameters, i.e., cathode excess O-2 ratio, turbomachinery efficiency, essure ratios. The results show the potential for an O-2-enriched system if the energy recovered reaches approximately 25% of the additional power consumption induced by the separation membrane. | es_ES |
