Highly Efficient Hydrogen Generation via Water Electrolysis Using Nanometal Electrodes
White Paper Summary Submitted by QuantumSphere Energy Research Laboratory, Sep. 15, 2006
Energy supplies in the 21st century will be challenged as fossil fuel reserves decline, human
consumption increases, and greenhouse gasses accumulate to further damage the atmosphere. These challenges will be met by innovative solutions to enable the hydrogen economy; to replace petrochemical fuels with hydrogen for use in fuel cells and internal combustion engines. One of the most difficult challenges is to produce hydrogen at a cost competitive with current fuel pricing (fossil or natural gas). QuantumSphere Inc. (QSI) has developed a disruptive technology to increase the efficiency of water electrolysis, utilizing its capability to manufacture high surface area nanometal particles (3-50 nm) by a scalable process. QSI has developed a unique electrode structure for alkaline water electrolysis by capitalizing on the enhanced surface area and catalytic reactivity of its nanometal catalysts. To date, QSI has already met the US Department of Energy (DoE) 2010 technical target of 75% hydrogen generation efficiency while eliminating the need for platinum precious metal catalysts which further reduces electrolyzer cost.
