Three different reactors are designed, manufactured and tested to investigate the effect of reactor design. The reactors are a tubular-shaped simple one, a tubular-shaped reactor with fins and a tubular-shaped reactor with liquid cooling channels. All of the reactors are filled with same amount of TiFe alloy and charged under various hydrogen supply pressures. The charging time and the role of the heat transfer mechanism are investigated by obtaining temperature histories which are measured at several points on the reactors. It has been found that the reactor design and activation process of metal-hydride alloy are significant parameters on the amount of hydrogen stored in the reactor and the elapsed time for storing. The charging time was 84% less, and storage rate was 39% higher for Reactor-3 compared to Reactor-1. The hydrogen storage rate was approximately 0.44% which is achieved at relatively low charging pressure of 12bar.
