A novel method of hydrogen generation by water electrolysis using ultra-short-pulse power supply is demonstrated. The ultra-short power supply consists of a static induction thyristor (SIThy) and a specific circuit which is called the inductive energy storage (IES) circuit. It was found that by using an ultra-short pulse with the width of 300 ns, electrolysis takes place with a mechanism dominated by electron transfer, which is different from the conventional diffusion limiting process in DC electrolysis.
