On-demand hydrogen generation by hydrolysis of sodium borohydride in batch reactors: effect of the buffer pressure. In: 3º Seminário Internacional de Torres Vedras, Hydogen Enegy and Sustainability-Advances in Fuell Celll and Hyfrogen Workshop, Torres Vedras, April 29-30, 2010, p. 24-27http://hdl.handle.net/10400.9/1127A study was undertaken in order to investigate the potential of hydrogen generation by hydrolysis of sodium borohydride in batch reactors, operating at moderate pressures, in the presence of a reused nickel-ruthenium based catalyst, to feed on-demand a proton exchange membrane fuel cell. The effect of the buffer pressure is explored and hydrogen generation rates are evaluated by changing catalyst amount, operating pressure and successive refuelingengHydrogen generationNaBH4PEMNi-Ru based catalystBatch reactorBuffer pressureFuel cellsconference object
