The presentation titled "Hydrogen Generation via Water Electrolysis Using Highly Efficient Nanometal Electrodes" covers recent research into the effect of the use of QSI-Nano(r) catalysts mixed with larger electrode components to give hydrogen generation efficiencies well above the U.S. Department of Energy's 2010 targets, and well ahead of the literature to date. The presentation will cover the basics of water electrolysis and provide data demonstrating the efficiencies of electrodes made from compressed nano catalysts. The most impressive data however is a new concept in electrode design known as Stingray, which runs at very high rates and exceptional efficiencies.

The patent pending portable device is a dramatic departure from conventional water electrolyzers used for hydrogen generation. New electrode and system design allows for nearly a sevenfold increase in clean hydrogen production, while maintaining efficiencies in excess of 85%. Achieving these levels of performance will help accelerate the hydrogen economy and could ultimately be used to generate clean burning fuel -- on demand -- for hydrogen fuel cells used in mass transportation.

This hydrogen generation breakthrough will be a presentation well worth attending!
