چکیده انگلیسی
Chemical hydrides, such as sodium borohydride (NaBH4)(NaBH4), offer promising gravimetric and volumetric hydrogen storage densities. The overall system energy density depends on the reactor performance. In this study, a novel intergrated reactor design in which catalyst bed is integrated with a heat exchanger for autothermal operation showed significant improvements in reactor performance. Over 200% enhancement in reactor throughput was achieved with the integrated reactor at 99% fuel conversion with constant reaction temperature profiles over a wide range of fuel flow rates. Impacts of improved performance on system operation and overall energy density of chemical hydride based hydrogen storage system were also discussed.
