Water-evaporation type cooling system based on electrolytic reaction and water-evaporation type cooling method therefor

A water evaporation type cooling system based on an electrolytic reaction, comprising:

• a hermetically sealed housing including a gas;
• solid electrolytic membrane means placed within said hermetically sealed housing to divide said hermetically sealed housing into first and second spaces, said solid electrolytic membrane means being constructed such that porous electrodes are provided on surfaces of solid high polymer electrolyte means allowing protons to selectively pass;
• a water-containing membrane formed within said first space;
• condensing means for condensing moisture, contained in the gas within said second space, in a condensing space communicated with said second space;
• water returning means for returning water condensed by said condensing means to said water-containing membrane made within said first space;
• a ventilation hole provided to establish a communication between said first and second spaces;
• and
• a direct-current power source for applying a direct-current voltage to between said porous electrodes on said solid-electrolytic membrane means.

A water evaporation type cooling method using a hermetically sealed housing including a gas and divided into first and second spaces by solid electrolytic membrane means having porous electrodes on surfaces of its solid high polymer electrolyte which allows protons to selectively pass, comprising the steps of:

• applying a direct-current voltage to between said porous electrodes to cause water electrolysis on a solid electrolytic membrane means surface at a first space side;
• transferring protons produced by the water electrolysis through said solid electrolytic membrane means to a solid electrolytic membrane means surface at a second space side;
• and
• causing a water production reaction to take place on said solid electrolytic membrane surface at the second space side to produce a difference in humidity between said first and second spaces to decrease the temperature of water reservoired in said first space.
