OSTI ID:7361824
A fuel cell is described 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; 3) an oxidizing gas circulating circuit for supplying oxidizing gas to the oxidizing gas chamber; 4) an electrolyte circulating circuit for supplying an electrolytic solution to the electrolyzing solution chamber; 5) a gas cooler; 6) a formed water tank whereby moisture formed in said generating cell, carried by said fuel gas into said gas cooler, and condensed therein will drip into said formed water tank; 7) an electrolyzing solution tank located in said electrolyte circulating circuit above said generator cell; and 8) 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. The gas leaked into the electrolyzing solution chamber is carried by the electrolytic solution flowing through the electrolyte circulating circuit upwards into the electrolyzing solution tank, where it is easily separated from the electrolytic solution, and electrolytic solution leaked into the fuel gas chamber is carried by the fuel gas flowing through the fuel gas circulating circuit downwards into the gas cooler, where it is separated from the fuel gas and dripped into the formed water tank. An improvement comprising means for keeping the fuel gas pressure in the fuel gas chamber and the oxidizing gas pressure in the oxidizing gas chamber constant and equal is described.
