Benefits of technology

[0007]The crux of the present invention is to improve the conventional hydrogen-oxygen electrolyzing device and the electrodes thereof for enhancing the electrolyzing efficiency.
[0009]Another object of the present invention is to provide a hydrogen-oxygen electrolyzing device with the carbon paper electrodes thereof having two material changed outer surfaces respectively in which a pulse-width-module power supplier is utilized to stimulate the water molecules in the electrolyte with demodulation for the water molecules occurring the resonant electrolysis in the process of electrolyzing and enhancing the electrolyzing efficiency.

Problems solved by technology

The ways to produce the hydrogen and the oxygen are versatile, but it is most environmentally protective and energy-conservative with electrolyzing.
If the gas films stagnantly aggregate on the surfaces of the electrode to increase the resistance of electrolyzing, the exerted external voltage has to be increased to force the current passing through the resistance layer, and it results in decreasing the electrolyzing efficiency.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention is related to a hydrogen-oxygen electrolyzing device and particularly to a hydrogen-oxygen electrolyzing device and carbon paper electrodes each thereof with material changed outer surfaces.[0003]2. Brief Description of Related Art[0004]The District of Energy (DOE) of United States has changed the regulation regarding the electrolyzing efficiency of the water being electrolyzed as the hydrogen and the oxygen from current 45% to 75%, and the change will be in effect since 2010. The ways to produce the hydrogen and the oxygen are versatile, but it is most environmentally protective and energy-conservative with electrolyzing. Therefore, it is an extremely important goal to cooperate with the resource of renewable energy such as the wind power plant and the solar power plant to covert the water to the hydrogen and the oxygen as the storage energy effectively.[0005]The electrolyzing structure in the cur...
