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...
Fuel cell and hydrogen storage development for a wheel chair
Rangel, C. M.; Silva, V.; Luz, Paulo P. da; Franco, Alexandra; Azevedo, F.; Bosukov, L.In this paper are presented, the recent advances of a demonstration project that focuses on the implementation of a hybrid system for a wheel chair incorporating a fuel cell and a metal hydride hydrogen storage system. Advantages regarding weight reduction and greater autonomy are emphasized, apart from the use of clean energy and the drastic reduction in charging time, when compared with the system before conv...
