Fuel cell

Claim 2

In a fuel cell comprising: 1. a generator cell having a fuel gas chamber, an oxidizing gas chamber, and an electrolyzing solution chamber; 2. a fuel gas circulating circuit for supplying fuel gas to the fuel gas chamber of said generator cell; 3. an oxidizing gas circulating circuit for supplying oxidizing gas to the oxidizing gas chamber of said generator cell; 4. an electrolyte circulating circuit for supplying an electrolytic solution to the electrolyzing solution chamber of said generator cell, 5. a gas cooler located in said fuel gas circulating circuit beneath said generator cell; 6. a formed water tank located beneath said gas cooler and in fluid communication therewith, whereby moisture formed in said generating cell, carried by said fuel gas into said gas cooler, and condensed therein will drip by force of gravity into said formed water tank; 7. an electrolyzing solution tank located in said electrolyte circulating circuit above said generator cell; and

Claim 3

a clean water tank located above said electrolyzing solution tank and in fluid communication therewith, whereby clean water can be supplied by force of gravity from time to time to said electrolyzing solution tank from said clean water tank in order to control the concentration of the electrolytic solution therein, whereby gas leaked into the electrolyzing solution chamber of said generator cell is carried by the electrolytic solution flowing through said electrolyte circulating circuit upwards into said electrolyzing solution tank, where it is easily separated from the electrolytic solution, and electrolytic solution leaked into the fuel gas chamber of said generator cell is carried by the fuel gas flowing through said fuel gas circulating circuit downwards into said gas cooler, where it is separated from the fuel gas and dripped into said formed water tank, the improvement comprising: a. means for sensing the level of electrolytic solution in said electrolyzing solution tank and b. means for opening the path of fluid communication between said electrolyzing solution tank and said clean water tank when the level of electrolytic solution in said electrolyzing solution tank is below a predetermined level and for closing the path of fluid communication between said electrolyzing solution tank and said clean water tank when the level of electrolytic solution in said electrolyzing solution tank is above the predetermined level.

Claim 4

a clean water tank located above said electrolyzing solution tank and in fluid communication therewith, whereby clean water can be supplied by force of gravity from time to time to said electrolyzing solution tank from said clean water tank in order to control the concentration of the electrolytic solution therein, whereby gas leaked into the electrolyzing solution chamber of said generator cell is carried by the electrolytic solution flowing through said electrolyte circulating circuit upwards into said electrolyzing solution tank, where it is easily separated from the electrolytic solution, and electrolytic solution leaked into the fuel gas chamber of said generator cell is carried by the fuel gas flowing through said fuel gas circulating circuit downwards into said gas cooler, where it is separated from the fuel gas and dripped into said formed water tank, the improvement comprising: a. means for sensing the level of electrolytic solution in said electrolyzing solution tank and b. means for opening the path of fluid communication between said electrolyzing solution tank and said clean water tank when the level of electrolytic solution in said electrolyzing solution tank is below a predetermined level and for closing the path of fluid communication between said electrolyzing solution tank and said clean water tank when the level of electrolytic solution in said electrolyzing solution tank is above the predetermined level.
