    摘要： Electron exchangers are placed vertically or horizontally in a conversion cell and divide it into cathode gas chamber, liquid chamber, and anode gas chamber. One side of the electron exchangers is conductive, and the other side is nonconductive. Voltage is applied to the electron exchangers to convert the liquid conversion solution to gases at the side of the electron exchangers facing the gas chambers, and gases are released directly to the gas chambers. The electron exchangers have many puncture channels on the surfaces, and they are designed by critical surface calculations. The puncture channels have special designed patterns and are manufactured with a precision technology. In producing the same amount of final gases, our method is energy efficient.

    摘要： Water electrolysis catalysts having reduced precious metal loading which are highly active and stable and methods of preparing the water electrolysis catalysts are described. The methods involve depositing a substantially continuous thin shell layer of a platinum group metal (PGM)-based precursor on a nano-sized inorganic oxide core to form a coated inorganic oxide core. The coated inorganic oxide core is heated in the presence of a template to convert the substantially continuous thin shell layer of the PGM-based precursor to a substantially continuous thin shell layer of PGM oxide. The template is then removed forming a water electrolysis catalyst comprising the nano-sized inorganic oxide core having a substantially continuous thin shell layer of the PGM oxide. The water electrolysis catalyst comprises less than 30 wt% of the PGM oxide.
