In recent years great attention has been addressed to the ammonia as a promising hydrogen carrier to realize next generation refueling stations according to a carbon-free energy economy. In this paper two hydrogen production units for small size refueling stations (100 kg/day of H2), based on ammonia feeding, are studied and their performances are compared (figure 1). In the first one the hydrogen is co-generated with electricity in a SOFC power unit [1] and in the second one the hydrogen production unit, based on an ammonia cracker [2], is integrated with a PEM power unit [3]. In both cases the fuel cell is sized to supply the electrical power for hydrogen separation and storage at high pressure. Table 1 summarizes the calculated performances that are quite similar for both the plants and differ only for the temperature at which the heat is available.

Abstract
In recent years great attention has been addressed to the ammonia as a promising hydrogen carrier to realize next generation refueling stations according to a carbon-free energy economy. In this paper two hydrogen production units for small size refueling stations (100 kg/day of H2), based on ammonia feeding, are studied and their performances are compared (figure 1). In the first one the hydrogen is co-generated with electricity in a SOFC power unit [1] and in the second one the hydrogen production unit, based on an ammonia cracker [2], is integrated with a PEM power unit [3]. In both cases the fuel cell is sized to supply the electrical power for hydrogen separation and storage at high pressure. Table 1 summarizes the calculated performances that are quite similar for both the plants and differ only for the temperature at which the heat is available.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
