Hydrogen generation by electrical discharge through metal/water system is a viable method for on-demand applications. But its success depends on high energy efficiency defined as the ratio of the amount of consumed metal for a complete reaction with water to the electrical energy input. To improve the energy efficiency the electrical discharge has to sustain the hydrogen generation reaction with a minimal energy dissipation. Some experimental results on the discharge voltage-current profiles are reported and discussed.
