A sodium borohydride hydrogen generation reactor for stationary applications: E...
Sousa, T.; Fernandes, Vitor R.; Pinto, P. J. R.; Slavkov, Y.; Bosukov, L.; Rangel, C. M.Ruthenium on nickel-foam catalyst was prepared for hydrogen production from the hydrolysis reaction of an alkaline NaBH4 solution. Experiments were carried out at five temperatures (30, 40, 45, 50 and 60 °C) in a 0.1 dm3 small batch reactor. To understand the kinetic behaviour of the hydrolysis reaction in the presence of this catalyst, the experimental data were fitted to three kinetic models (zero-order, firs...
Novel hydrogen generator: storage based on metal hydrides
Rangel, C. M.; Fernandes, Vitor R.; Slavkov, Y.; Bozukov, Latchezar N..A novel electrochemical system has been developed which integrates hydrogen production, storage and compression in only one device, at relatively low cost and high efficiency. The prototype comprises a six electrode cell assembly using an AB5 type metal hydride and Ni plates as counter electrodes, in a KOH solution. Metal hydride electrodes with chemical composition LaNi4.3Co0.4Al0.3 has been prepared by high f...
Integrating hydrogen generation and storage in a novel compact electrochemical ...
Rangel, C. M.; Fernandes, Vitor R.; Slavkov, Y.; Bozukov, Latchezar N.A novel electrochemical system has been developed which integrates hydrogen production, storage and compression in only one device, at relatively low cost and high efficiency. The development of efficient and reliable energy storage systems based on hydrogen technology represents a challenge to seasonal storage based on renewable hydrogen. State of the art renewable energy generation systems include separate ...
